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

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.

Thanks for your information,
