With Radeon 9200SE I'm not able to use X, apparently because its memory can't be used. With any kernel (tried 2.6.32, 3.0.0, 3.1-rc6) I will get dmesg lines about overlapping. [ 0.073187] pnp 00:00: disabling [mem 0x000cd000-0x000cffff] because it overlaps 0000:01:00.0 BAR 0 [mem 0x00000000-0x0fffffff pref] [ 0.073205] pnp 00:00: disabling [mem 0x000f0000-0x000f7fff] because it overlaps 0000:01:00.0 BAR 0 [mem 0x00000000-0x0fffffff pref] [ 0.073223] pnp 00:00: disabling [mem 0x000f8000-0x000fbfff] because it overlaps 0000:01:00.0 BAR 0 [mem 0x00000000-0x0fffffff pref] [ 0.073241] pnp 00:00: disabling [mem 0x000fc000-0x000fffff] because it overlaps 0000:01:00.0 BAR 0 [mem 0x00000000-0x0fffffff pref] [ 0.073259] pnp 00:00: disabling [mem 0x00000000-0x0009ffff] because it overlaps 0000:01:00.0 BAR 0 [mem 0x00000000-0x0fffffff pref] [ 0.073277] pnp 00:00: disabling [mem 0x00100000-0x1ffeffff] because it overlaps 0000:01:00.0 BAR 0 [mem 0x00000000-0x0fffffff pref] This happens always and then I can't use X. It will tell me that no screens was found. System works fine with ATI Rage 128VR (32MB, PCI). With 2.6.32 I get also: [drm] Detected VRAM RAM=0M, BAR=0M and with 3.0.0: [drm] Detected VRAM RAM=128M, BAR=0M 3.1-rc6 doesn't seem to have anything about this. Otherwise they seem to be correct. System I used has Gigabyte GA-6BXE motherboard (rev 2.1, Intel 440BX chipset) and VIA C3 (1 GHz, Nehemiah-core) in addition to Radeon 9200SE (R92LE, 128MB). BIOS is the latest available from Gigabyte. OS is Debian Wheezy with Experimental kernel (for testing). I have already reported this to Debian as bug #641176.
