Thanks for everyone who sent me copies of Manuel's driver :-)  Turns out
to have been a nameserver issue on my end which I am painfully aware of
(and which Network Solutions still hasn't gotten fixed up after over
a month of trying to get them to do so... sigh...)

Anyway... it seems to work quite well on my AlphaStation 200, getting
around 14MB/s sequential reads.  I think the only thing I really need
to be concerned about is having 2 7200 RPM drives stuffed in close
proximity in the tiny AlphaStation 200 case :-)

Boot messages attached below for completeness.
