Many thanks for the link.

Firstly I found that I was resuming immediately - I think this was due to PCI 
wakeup - after disabling that in the bios I got suspend working.

I've also got resume working ... well sort of.  On resume I get a shell but 
lots of I/O errors to my (sata) disk.  So it looks like a sata driver issue.

Googling, it looks like I might need 2.6.19 kernel ... not sure if there is a 
convenient deb for mythbuntu.
