I wasn't using the DMA, 32-bit, multi-block-16 flags on wdc. Added that.
still got the drops..

I removed the ed0 ISA card from the kernel, seemed to reduce freq. still 
dropped.

I then tried harder to look for a correlation. doing virtual desktop pans
caused every drop every time. small incremental moves fine, but a complete
X11 redraw triggers things.

I'd say I have the X11 bug.

If I can do any useful debug (since I can re-create this) let me know. If
this is a dead horse, I can live with it.

cheers and thanks for advice!

-George
