I experienced (reported here earlier) a problem with my CD-ROM drive; it
worked fine using the Cardbus chip in PCMCIA mode, but it hung when it
used the native carbus chip driver.  However, in this case my Lucent
WaveLan works fine in either mode, so maybe that's not the problem.  But
maybe it's worth trying to take the Cardbus driver out of your kernel
to see if it works when using the "native" PCMCIA driver.
