No 'Net access at the moment, but I best note this before I get
distracted.

The SiS 550 chip (VXL/Percio thin client hardware, I had the details
of its actual origin, but not at my fingertips right now) responds
quite well to VESA.  I get 1024x768x32 on an old 14" SVGA monitor.

The CPU hardware needs *noe820scan=.

The VXL itona ought to be more promising, but is in fact
disappointing.  Using the same monitor, the best I can get is
800x600x16.  No need for *noe820scan=, on the plus side.

In passing, the /386/9pcdisk.gz kernel (my version is dated 11/11
03:25, local time) does not recognise the VESA device, complains about
/dev/realmode.  I've submitted a patch with a change to
/sys/src/9/pc/pcdisk that moves "realmode" and seems to create a
working version of "9pcdisk.gz".
