Why use initrd?  Why not allow a file name to be passed to the kernel at
boot a la acpi=off, acpi=mydst.hex or whatever?  Put the file in the
/boot directory?

I think that this is not possible. The filesystem would have to be
accessible which is not the case at the early stage where ACPI loads
(there could even be the case, that no interrupts are assigned yet, to use
the scsi controller where the partition with the file is stored). Not to
mention, that harddisk and scsi drivers are loaded much later anyway.
The initrd is the only sane way to do this. I could also change my patch
to accept a plain DSDT file, without my 'magic' signature, if no other
initrd data is present.

Or make the acpi=file.hex boot argument refer to a file within the
initrd image. Then its just a case of getting mkinitrd patched to look
for /boot/dsdt.hex by default, and letting the user specificy an
alternate DSDT by parameter and generating initrd's would be a simple.
