Nice, with that (removing uhci_hdc and ehci_hdc modules) I can enter in suspend mode successfully, but when I go out of it, my screen is not recovered.

I'm running stock Debian kernel 2.6.8-1-686. I'll have to try also with a vanilla kernel and those patches. Thanks a lot for your hints. -- Jose Carlos Garcia Sogo jsogo@debian.org
