2.6.18.1 hangs after resuming from apm suspend

[Christian stahl <stahl23@web.de>]

After upgrading from 2.6.16.20 to 2.6.18.1 my Siemens Scenic
Mobile 750AGP Notebook hangs after resuming from suspend.

However resuming from suspend works properly if:

- the prism 2.5 WLAN card is removed before suspending
- the prism 2.5 WLAN is removed after resuming


Here's the content of /proc/interrupts:
