It will work if vesa is kldloaded _before_ suspend.

Restarting moused after resume is must. pccard and ndis powered broadcom card do not work after resume, even if right driver was never loaded during/after boot - before suspend. Main problem is that shutdown button (S5) doesnt work after resume. Is there any know reason why that could happen? -- Paul
