The ps2 utility is available at the IBM website. Just search the 
downloads for your TP model number. You will need a bootable DOS 
partition, floppy or cdrom for this.

Yes, it's a TP600e (model-no. 2645-8A0).

`ps2 pciirq 10 11'

Disable modem, midi, serial ports, parallel port and audio for testing
(use `ps2 ? irq' to list any irq used by the TP and turn anything off
that you don't need).

The above setup puts uhci0 and cbb0 on irq 11, and cbb1 on irq 10 for 
me. As long as I don't use cbb0, I don't get any interrupt storm 
messages and there are no device slowdowns.

I didn't do any further tests to get the other cardbus slot working  
without device slowdowns as well. But I'm sure that it is resolvable
through further playing with the irq setup.

The important thing here is not to give up testing until you have
a working IRQ setup.

GENERIC, with NEWCARD enabled and useless stuff commented out.
Watch to load snd_mss, usb and network devices as modules to 
get suspend working.

Default device.hints with acpi enabled, apm disabled.

I don't think it'd be helpful in any way to post it here.
If you really need it, drop me a mail.

I didn't customize anything in the sources that has to do with the 
TP600E.

As long the message is your only problem with no device slowdowns coming 
up, just ignore it.
