Sure!

root@babar:/usr/src/linux-2.6.25# patch -p1 < /home/pat/patch-2.6.26-rc3.gart-suspend
patching file arch/x86/kernel/pci-gart_64.c
Hunk #4 succeeded at 629 with fuzz 2 (offset 11 lines).

.....make; cp bzImage /boot; reboot....

without mem=4G:
...
[17180761.682783] CPU1 is down
[17180761.682968] Class suspend failed for gart0
[17180761.683321] PM: Some devices failed to power down
[17180761.683326] Enabling non-boot CPUs ...

with mem=4G:
...
[no change]

-> perfect! Behaves as you predicted.

logs are ... here: http://zefir.890m.com/dmesg/ *

Cheers
