adding aacraid support for i386 bf

[Fabrice LORRAIN <Fabrice.Lorrain@univ-mlv.fr>]

Hi,

As of kernel-source-2.2.19-7, aacraid support as been added (thanks
Herbert).

Could you add it for the next build of the boot-floopy so I can test it?

For those interrested, aacraid is a patch to support adaptec raid carte
used in Dell Poweredge serveur, among others.

Thank's,

	Fab
