This is a boot loader problem; it is a bug in grub which they seem to
refuse to acknowledge and hence won't fix even though it has existed
for ages.  The boot loader is passing a bogus "mem=" option to the
kernel that causes resources to be allocated for your CardBus bridge
that conflict with a reserved memory region.

Add:

    reserve=0x3ffe2800,0x1d800

to your kernel boot parameters and you should be ok.
