USB cards for PWS 433au



I recently retired an old AMD K6-III/450 system that had a serviceable
USB controller in it, so I tried transplanting it to my Alpha.  The
kernel seems to detect it just fine and load the appropriate drivers,
but there's evidently a conflict of some kind between the USB card and
my Radeon 7500.  Most solid regions of a KDE session screen have
vertical bars through them, and there is some strange tile "shading"
going on when I fire-up "kmahjongg".  As far as the behavior of the USB
controller, I tried plugging-in an external USB harddrive that is known
to work properly with that controller card: the drive seems to work fine
until I attempt to write to it, at which point the system takes the
drive off-line, and nothing short of a system reboot allows it to work
again.

Any tricks I should know about to get things working?  Maybe a BIOS
setting of some kind?  I'm to the point of ripping out the USB card to see
if proper graphical console functionality can be restored :-(.  Here's the
"lspci -v" output (non-root user) for my system:
