This beast apparently has an SiS 315 chip, if the wubs are to be 
believed?  Which I guess explains this...

(retching noise)

The more portable thing would be to use pciaccess' I/O port routines, 
which avoid this entire trap (for exactly this reason), and then wire up 
the legacy_io file in sysfs.  That's not going to be a small amount of 
typing in the sis driver though.

Alternatively you could hide the legacy I/O handle inside lnx_video.c 
for arches like this and mangle the {in,out}[bwl] macros appropriately. 
  Possibly less typing, arguably less ugly.
