I see now what you mean: kernel occasionally oopses when I
insert a PCMCIA card, like this one:

pccard: PCMCIA card inserted into slot 1
pcmcia: registering new device pcmcia1.0
pcmcia: request for exclusive IRQ could not be fulfilled.
pcmcia: the driver needs updating to supported shared IRQ lines.
Unable to handle kernel paging request at virtual address c0a80ff0

the TEA is in range of the address returned by  p3_ioremap() of
area 5/6.

It's very hard to reproduce reliably, it sometimes just happens :(
