stupid amd64 vs i386 hardware question

[Didier Wiroth]

Hello,
I'm planning to get a SAS controller, which has a LSI-SAS-1068E chip.
The controller should be running on current, on the amd64 arch.
The LSISAS1068E chip is only mentioned on the i386 hardware support page.
Sorry for the questions ... ;-/ but
1) does it mean that it won't run with a amd64 kernel ?
2) by the way ... do all the i386 supported driver run on the amd64 arch or
not?
