I just had a look through the svgalib.c. It makes a lot of calls to
vgastate with the NULL parameter for the vga iobase, I guess that's
definitely why it's crashing the driver. 

Also, svga.h has inline functions that needs modifying. Looks like a big
change to let it work with the vga iobase or NULL. Perhaps just passing
the par->state.vgabase into those functions could make it work. Usually
this gets initialised as zero at boot or driver load so the default
could be NULL anyway for those drivers that assume it is located at 0.
