I though that its possible to use the ext2 filesystem to use with initrd>? Is there
an advantage of using the minixfs filesystem over the ext2 filesytem in this
application?

Anyway, I just want to make an initrd so that I can have etx2 and ReiserFS support
compiled as modules and also load a frame buffer module at boot time.

Most of this can be done through mkinitrd, the configuration file are a little
complicated though.....
