How much memory do you really have in the machine? 0x1e000000 is an
odd top of memory value - that's 480MB. I suspect you actually have
512MB, in which case you want to do:
reserve=0x1e000000,0x02000000
to force resource allocations to be above the RAM.

If the above works, the cardbus resource management is working just fine.
What isn't working is that the kernel doesn't have a complete picture
about what areas of system memory are actually allocated and in use for
other devices.
