Good news - so the USB2.0 code has been backported.  I will give it a

Unstable system...  The IDE controllers (not RAID controllers) don't
switch into DMA mode...  

I don't remember as what the chipset is identyfied.  I can check on
this though.  A while back I noticed that the VIA 333 chipset was
identified as a VIA 266 chipset.  It mostly ran fine but didn't feel
perfectly stable.  Running Intel chipsets may be a better choice - but

those of us who need lots of fast X87 instructions like the AMDs.

Many of my problems have started recently with USB 2.0, Firewire, and
the new AMD chipsets.
