Another oddity: the NC driver is running as a loadable module, as is
USB.  Usb and eth0 show up in the proc irq list, but the video irq is
conspicuously absent (no irq 11).  <scratches head>

It *does* show up however, in /proc/pci

Bus  1, device   0, function  0:
  VGA compatible controller: ATI Unknown device (rev 0).
    Vendor id=1002. Device id=4d46.
    Medium devsel.  Fast back-to-back capable.  IRQ 11.  Master Capable.
    Prefetchable 32 bit memory at 0xe8000000 [0xe8000008].
    I/O at 0xcc00 [0xcc01].
    Non-prefetchable 32 bit memory at 0xfcffc000 [0xfcffc000].

My intuition is that the phenomenon is triggered by certain sequences of
display attribute control characters generated from the html browser.  When
it happens with lynx, if I scroll up or down far enough to get the offending
attributes out of the view window, the flashing stops.
