Here's some patches to get POST working with XGI Z9. I have tested them
with the following card:

I'm using the card on an ARM board where the bootloader knows nothing
about VGA or VGA BIOS, so having POST support in the kernel driver
is mandatory. With these patches the memory size is correct detected,
R/W test passes and it's possible to use e.g. framebuffer console.

sisfb: move XGI POST RAM type detection into a subroutine
sisfb: add subroutine for detecting XGI Z9
