I know that those models of VAXen don't like SCSI drives over 2GB because of
the set of SCSI commands they understand.

So yesterday I did this. Installer ran its course fine but the system would
not boot - kernel hangs right after bootloader messages, before the kernel
itself prints anything out. Then I remembered this same thing happened with
8.0 and I actually fixed it, but apparently my patch was never incorporated
and thus I need to build a custom kernel for it to actually boot. Back then,
Ragge asked me to send him a diff so he could commit it, which I did, but
looks like it was forgotten.

Here's a link to a diff against 8.0 that will probably apply just fine to
9.0.
