[9fans] A note about AMD64 mainboards and Plan 9

[Vester Thacker]

For anyone thinking about running Plan 9 on an AMD64 mainboard, 
ensure that you don't purchase a mainboard with the VIA VT800 
chipset. The VIA VT800 chipset is not supported by Plan 9 at 
this time. Unless you plan to write a driver for it.

The AMD64 mainboards that have nForce3 150 chipset work well.

I just wanted to share my findings with others in attempt to
save you from the expensive mistakes that I have made.

What's wrong with this chipset ?
I've bought an Acer Aspire 1502 notebook with a KT800 chipset inside,
and beside the broadcom ethernet (and wifi) missing drivers, it runs
Plan9 quite fine.

         Philippe,

I spoke too soon about nForce3. I'm having slightly different 
problems now. I'd like to retract my earlier statement. I
apologize.

I believe the KT800 and VT800 are different. It's been my experience
that they exhibit slightly differing behaviors. For example, my keyboard
and mouse become inoperative shortly after the boot prompt with the
VT800 and the same problem occurs once rio starts with the KT800. I 
can't explain it.
