hi

the problem on your laptop is resource assignment:
	[4294701.611000] Yenta: ISA IRQ mask 0x0000, PCI irq 0
	[4294701.611000] Socket status: 00000000
that socket status has to start with a 3. it does not because the driver is
not talikng to the cardbus bridge.

it's because your BIOS is providing the kernel a wrong e820 memory map which
means the cardbus controller i/o memory overlaps with physical memory.
this can be solved by the right reserve= parameter on the kernel command line.
unfortunatley that part in dmesg is already gone after boot in your case.
so you need to give me that part from /var/log/messages. it should look
similar to this:

  DMA zone: 4096 pages, LIFO batch:1
  Normal zone: 61424 pages, LIFO batch:31

with that info from your laptop i should be able to give you the right
reserve= parameter.
