This is very cool! I wasn't expecting hp300 to go ELF so soon after
mvme68k, I was expecting something like a couple of months.
btw, I'm definitely waiting for the snapshot as my feeble attempts at
building one failed miserably on (I was going from 1.5 to current):
1. Twice panic'ed with bad_dir(), and since I was in X (XhpBSD) the
keyboard didn't respond with ddb. No core.
2. Couple of panics with softdep, worklist_remove().
After that my root disk was hosed properly and it was faster to reinstall
than to mess with all the files in /lost+found. After re-install I was
sure *not* to have softdeps enabled in /etc/fstab but when mounting a cd
# mount -t cd9660 /dev/sd3c /cdrom
I got the softdep worklist_remove panic again. I'll try to panic it again
and maybe file a proper PR. I *want* softdeps ( & UBC) to work, as
disk ops on hp300 aren't exactly optimal :).
It does not panic on kernels without "options SOFTDEP".
This was just a FYI if someone else is seeing frequent panics.

Seconded, and thanks for the work!
