Sorry to be late, but I had to switch to another activity.
I made some tests with the lastest build (4.7.99.3). The PC (Dell GX270)
is
cold-started between each test, since it seems that a simple reboot
doesn't
reset the BIOS.

A question to the person who started this thread: Does setting the
"VideoRam" option in the "Device" section of the XFree86 configuration
file to 32000 and not running 865patch help?
Test with VideoRam set to 32000 in the config file and 865patch not
started.
Here are the significant log lines (I can send the whole file upon demand)
:
(II) I810(0): VESA VBE Total Mem: 8064 kB
(WW) I810(0): Detected stolen memory (8000 kB) doesn't match what the BIOS
reports (8064 kB)
(II) I810(0): Will attempt to tell the BIOS that there is 12288 kB
VideoRAM
(WW) I810(0): Extended BIOS function 0x5f11 not supported.
(II) I810(0): BIOS view of memory size can't be changed (this is not an
error)
(**) I810(0): VideoRAM: 32000 kByte
(--) I810(0): Maximum frambuffer space: 31832 kByte
(--) I810(0): Maximum space available for video modes: 8064 kByte
(II) I810(0): VESA VBE Total Mem: 0 kB
(II) I810(0): BIOS call 0x5f05 not supported, setting refresh with VBE 3
method.
What is strange here is the second "VESA VBE Total Mem:" line, which
indicates 0 kB !!!
Yes, that's what your prior logs reported.
Then, if I switch to the text console and back, the crash is still here :
(WW) I810(0): PGTBL_ER is 0x00000029
This is new.

Fatal server error:
Server aborting
After the crash (without reboot), X starts again (since it's respawned by
init)
and here are again the significant log lines :
(WW) I810(0): Bad V_BIOS checksum
(II) I810(0): VESA VBE Total Mem: 0 kB
(WW) I810(0): Detected stolen memory (8000 kB) doesn't match what the BIOS
reports (0 kB)
(II) UnloadSubModule: "int10"
(II) Loading sub module "int10"
(II) I810(0): VESA VBE Total Mem: 12288 kB
(II) I810(0): Tweak BIOS image to 12288 kB VideoRAM
(==) I810(0): VideoRAM: 65536 kByte
(--) I810(0): Maximum frambuffer space: 65368 kByte
(--) I810(0): Maximum space available for video modes: 12288 kByte
(WW) I810(0): Extended BIOS function 0x5f05 failed.
So I think the 865patch is still need for the 865G on the Dell GX270.
This is not a problem for me, as I previoulsy stated, since at
installation
time (RedHat's anaconda), the Video Memory isn't always correctly detected
(and it's perhaps to confusing for the end-user).
So I prefer not to use this configuration option and use the 865patch.
(Marc)
Indeed. The problem is that zero isn't recognised as a valid
TweakMemorySize() return. The attached, which I've already committed,
should fix this.
I'm not sure, since every time I don't use the 865patch, with or without
the VideoRam parameter, I get these messages on the second int10 launch
(before drmOpenDevice).
(WW) I810(0): Bad V_BIOS checksum
(II) I810(0): VESA VBE Total Mem: 0 kB
And the crash still occurs after switch to text console and back.
Please post the _complete_ log.
Marc.
