That's a rather old version of the driver.  My is that it has been
updated with parts from newer drivers, but I can't be certain what the
changes are.

Bug in the PCMCIA code...
I find that with 2.4 in-kernel PCMCIA code I must physically remove all
cards before restarting PCMCIA or suspending the laptop.  (Grrrr, this
worked perfectly for years.  Linux did have the best PCMCIA
implementation around, and the MS-Windows people were the ones that had
to remove devices before suspending.)

I believe that the transceiver power needs to be enabled.  The
INVERT_LED_PWR and INVERT_MII_PWR per-card flags were added in the very
next version of the driver, in May 2000.
