No, I don't think. The delay I observe is on resume (suspend is very
fast). Moreover, I have no SATA. It seems that my problem came from
pcmcia.

Uf, I will try to find the time. I am on my way to try to compile
2.6.21.2 now. Problem is that a kernel compile "the ubuntu way" last
hours here. If there is an expert on make-kpkg here, I could use some
advise. I'd prefer to test patches over a 2.6.21 stable release, to
avoid mixing symptoms from an experimental -rc...
