The bug is alive and kicking as of 2008-03-03 with 2.6.24-14-386.

When pcmcia card is inserted, dmesg shows:

last line comes after I pull the card (PCMCIA USB 2.0 card) out.

In terms of workaround, I would appreciate if someone finds a good
solution (disabling pcmciautils seems to invite breakage because it runs
as a service in several runlevels)
