I did get the drive to work on the PCMCIA slot with the 2.0.30
version of the kernel. It looks like the PC110 bios was the
culprit for the errors. If the drive is plugged into the PCMCIA
slot while powering it up, the bios makes the drive look like
a normal non-PCMCIA drive. It looks like this confuses the
kernel causing problems with the APM code (my guess) so the drive
never gets properly reset.

If I power up the machine with a 48MB CFlash card and later
plug in the drive in the PCMCIA slot the APM+PCMCIA services work
as usual.

So at this point I am happy that I have the extra room to put all
the fun stuff on (gcc, kernel, X11, xemacs 20.4, kde, etc. :) ).
I also was able to generate a swap file to use for enhancing the
low 20MB memory (can't believe this seems like low memory to me

The performance with the new drive seems to be faster than before
so I can say I am reasonably happy. Now all I need is the
wireless cards to drop a little more in value and get them
faster :) .
