So far, so good. Why can't this motherboard boot off the SATA drive? And are
you sure your "remappinig" didn't block the CD drive from being seen?

Run this to see if any of the ATA or so-called IDE drives are detected.
        ls -ld /proc/ide/*/media
        grep . /proc/ide/*/media

Also, if it's a CD-RW burner, do *not* use that ide-scsi whackiness with the
2.6 kernel. 2.6 supports writing directly to ATA drives, as does the version
of cdrecord in the kernel.

You can change your NFS mount settings to use NFS version 3.

I've only had it with funky IDE hardware, but I've seen real oddness with
the ide-scsi module loaded.
