Neither would I - the inaccuracies involved in moving a ten foot pole with
enough precision would most likely damage the card.  It's much easier to
get it in the slot if you touch it with your hands directly, and after
that you don't really need to touch it at all.

Thanks for the warning on the 2.1.x kernels, though... my main FTP
server's got about 40GB of disks hooked up to an AHA 2940.. it runs 2.0.33
now, 2.0.30 previously, and even with 500 simultaneous downloaders, the
2940 never failed me.  I hope they fix that driver for 2.2 or something,
otherwise I'll have to patch the 2.0.33 aic7xxx code back in :)

What is the cause, anyway?
