After some more experimenting with different versions, I'm getting odd

FYI, what I see is:
* as noted, commits before bb6355 work fine (ie up to 3.4-rc6).
* including commit bb6355, graphics freeze on the first transition after
grub (Plymouth?)
* the very next commit makes the (plymouth?) splash screen work, but the
greeter screen display is corrupted; ctrl-alt-f2 works - if pressed
immediately
* this situation continues up until release v3.5^. But building v3.5 itself
works perfectly! Presumably I've done something wrong here..
* v3.6-rc3 displays the splash (plymouth?) screen fine, but instead of a
greeter screen, screen goes blank.
I'll try to make some more sense of this in the next few days - but
suggestions are welcome.
Sorry if I'm posting this in the wrong place - let me know if I should
create a bugzilla entry or whatever.

Does patch
http://people.freedesktop.org/~glisse/0001-drm-radeon-extra-type-safe-for-fence-emission.patch
Helps ?
Thanks Jerome. Will try patch tonight or tomorrow morning.
How do I check whether the radeon is on an AGP bus?
The lspci output does not mention AGP; line for video controller is:
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee
ATI M56P [Radeon Mobility X1600]
The "lshw" output also shows no signs of AGP.
The dmesg output contains "[0.909546] Linux agpgart interface v0.103"
but otherwise no mention of "agp" or "AGP".
By the way: tested the 3.5.3 release made today : still corrupt
graphics. And the v3.5 release (which was oddly working) also showed the
same corrupt graphics as soon as I forced a rebuild of the initrd -
maybe an older radeon module somehow ended up in the initrd built by
"make-kpkg --initrd".
Regards,
Simon
