try adding iommu=soft to your kernel parameters, boot and then try and suspend(this is a blind shot)

No, you have to add that string in the kernel line you are using in /boot/grub/menu.lst

For example:

title Ubuntu 8.04, kernel 2.6.24-19-generic
root (hd0,1)
kernel /boot/vmlinuz-2.6.24-19-generic root=UUID=173b7dcf-b906-4a98-a530-d7c871b6b414 ro splash
initrd /boot/initrd.img-2.6.24-19-generic
quiet

will become:

title Ubuntu 8.04, kernel 2.6.24-19-generic
root (hd0,1)
kernel /boot/vmlinuz-2.6.24-19-generic root=UUID=173b7dcf-b906-4a98-a530-d7c871b6b414 ro splash iommu=soft
initrd /boot/initrd.img-2.6.24-19-generic
quiet

or you can add that to the kernel parameters list in the GRUB boot menu (press 'esc' at boot time, select the first kernel and press 'e', you could add iommu=soft here)
