2.4.21 and 2.5.74 freeze on cardmgr start

[Wichert Akkerman <wichert@wiggy.net>]

I bought a new laptop recently (dell latitude d600) which seems to be
working reasonably well with Linux, with PCMCIA as the big exception.

When I start cardmgr I see log messages for IO port probes and than the
machine is completely frozen:

Starting PCMCIA services: cardmgr[309]: watching 2 sockets
cs: IO port probe 0x0c00-0x0cff: clean
cs: IO probt probe 0x0800-0x08ff:

At this point neither magic sysrq nor the hangtimer work. This
behaviour occurs with all of 2.4.18 (debian boot-floppies kernel), 
2.4.21, 2.5.73 and 2.5.74 (all unpatched).

Obligatory lspci output:
