Thanks for your /proc/interrupts file.  You have a lot less IRQ
sharing than me:

           CPU0       
  0:    5484369          XT-PIC  timer
  1:      13698          XT-PIC  i8042
  2:          0          XT-PIC  cascade
 11:     301909          XT-PIC  uhci_hcd, uhci_hcd, uhci_hcd, Intel 82801DB-ICH4, eth0, yenta, yenta, radeon@PCI:1:0:0
 12:      14446          XT-PIC  i8042
 14:      63403          XT-PIC  ide0
 15:         21          XT-PIC  ide1
NMI:          0 
ERR:          0

I wonder why the system has got such a high affinity to IRQ 11.  I've
never seen so much IRQ sharing before. 8-/

I'm going to give it a try without the radeon DRM module.

By the way, here's a log message from the system when it tries to come
back from suspend:
