Which qemu version?  Which seabios & vgabios version?

Windows xp booting in 4bit usually indicates VBE doesn't work at all, 
trying to enable vesafb in linux fails too then.

I havn't seen this for a *long* time.  Last time was a year or so back, 
while shaking out vgabios issues.  Especially I've never seen that with 
any qxl/spice stuff in upstream qemu.  Thats why I'm wondering where 
this comes from?
