This patch set makes sure that FB drivers for PCI devices utilizing
the svgalib interfaces work on multi-domain PCI architectures.
Basically this amounts to making sure that the vgastate->vgabase
__iomem pointer makes it way into every interfaces and gets used
by all of the I/O access calls.
jeez, that was fast work! I'd already done the changes in s3fb.c but
didn't get as far as you did with this.
I'm now testing your patches right now.
Thanks a lot in advance for testing Alex.
With your patches, this happens:
