Subject[bug report] pcmcia in kernel 2.4.0-test8
Summary:

Kernel pcmcia code doesn't work.
DHinds pcmcia code works only if kernel pcmcia code is completely
disabled.
USB Pegasus driver fails when kernel pcmcia code is enabled.

Attached is a text writeup of several tests.

"The difference between 'involvement' and 'commitment' is like an
eggs-and-ham breakfast: the chicken was 'involved' - the pig was
'committed'."
