Yes, I have noticed this too on my T30. I wonder if it has something to
do with these kernel boot-up messages:

Jul 11 17:17:24 calliope kernel: PCI: Cannot allocate resource region 0
of device 02:00.0
Jul 11 17:17:24 calliope kernel: PCI: Cannot allocate resource region 0
of device 02:00.1

lspci -v reports:

02:00.0 CardBus bridge: Texas Instruments: Unknown device ac55 (rev 01)
02:00.1 CardBus bridge: Texas Instruments: Unknown device ac55 (rev 01)

Are you using the yenta socket from the kernel or the pcmcia_cs package?
(I am using the kernel pcmcia support).
