Xorg log

I'm experiencing this: http://img354.imageshack.us/my.php?image=dscf0434ju7.jpg
On Debian (which, as far as I heard uses VGA console), I experience this on VT
switch, while on Arch I only get this on shutdown (probably because Arch uses
vesafb console).
This is Biostar TA780G M2+ (AMD 780G chipset), AMD Athlon 64 X2 4000+, 4GB RAM.
Memory for onboard graphics card is set to "Auto" in BIOS.

From what I have heard, this doesn't occur on all cards; it is apparently a
hardware issue, but direct VGA access could be implemented to work around this.

I'm attaching Xorg.0.log, which mentions that card doesn't properly deal with
memory access:
RADEONHD(0): RHDVGASave: VGA FB Offset (0xC0000000) is out of range of the
Cards Internal FB Address (0xD0000000)
