Yes. If this patch works for tohers, then we can move it into
pci_default_resume during the cleanup.

No. I meant VESA frame buffer. And it also works w/o framebuffer
(std VGA).

I am still wondering why it doesn't work for Alexander. 
Alexander: Is your card sitting on PCI or AGP?

Thanks,

I guess we need to do something like this "acpi_sleep=vgapost", 
rather than doing a generic vgapost for all display devices. 
As the generic solution seems to have broken few systems 
which were working before.

I have two systems with almost identical video setup, with 
Radeon 9000M AGP adapter. vgapost works on one system and 
fails on another. The failing system never returns 
from real mode vgapost call. I also found that 
the VBIOS is not same on these two systems. Probably 
different versions of the firmware. I am digging further 
to find out why it works on one Radeon 9000M and not 
on another one.

I used the patch that exports vbios through sysfs and got 
hexdump of vbios on the two systems. 
[Look for Jon Smirl's patch in lkml, subject - "add PCI ROMs to sysfs"]

I somehow assumed that user-mode vgapost wont work on this system either.
I need to go and check it now...

Yes. It works with this utility and with posting from X radeon driver.
It works on both the systems.
Only the vgapost from kernel, hangs on one of these systems.

No difference in lspci at all. Both of them sitting at 1:0.0.
