This is something I've also had a problem with on my computer. I think
it's a bug in MySQL or something, it doesn't support the sleep state
properly or something. I believe a fix is to stop it with a
'pre-sleep' script and start it with a 'post-sleep' script.
If you do solve this one, please let me know, although I don't sleep
my AMD64 anymore.

Hibernate was fairly easy. In the kernel config I set my default
resume partition to the swap partition. Then stopped mysql, and
hibernated (by echo S5 or something into /proc/power or somethine),
then started it up and watch it resume fine, restarted MySQL. I only
played with it but found it really easy.
