I can confirm this bug on a Thinkpad T42p 2373-KYG
on Kubuntu 7.04 Feisty Fawn, uname -r: 2.6.20-16-386; with ATI driver 8.38.7
(installed via Envy)
Reducing the image_size does make supend-to-disk work.
But after resuming form supsend-to-disk, the sound is gone and it seems to me
that the available RAM is not used any more: I mean the systems starts swapping
earlier
compared to RAM/Swap usage after a fresh reboot.
