[LinuxBIOS] Problem with VGA initialization

[Patrick Georgi]

Hi,

I tried running linuxbios v3 in qemu again, and for some reason it
didn't initialize the pcivga device, even though I have vm86 compiled
in.

See this excerpt from the log:
Phase 3: Enumerating buses...
dev_root_phase3 missing 'ops' initialization
Phase 3: Failed.
Show all devs...
Phase 4: Allocating resources...
Phase 4: dev_root missing ops initialization
Phase 4: Failed.
Show all devs...
Phase 5: Enabling resources...
Phase 5: Done.
Show all devs...
Phase 6: Initializing devices...
Phase 6: Devices initialized.
Show all devs...


I think, that the "missing 'ops' initialization" message indicates that
the static initialization in the source didn't survive the build.

I'm at r542, vgabios-cirrus.bin is a patched variant (includes the pci
header), it's built using ubuntu's gcc-4.1.3(preview) on amd64.

Any hints?

Regards,
Patrick Georgi
