Okay, in 5.0RC2, machdep.c:cpu_reboot() calls
kern_subr.c:doshutdownhooks(), which is what calls
pmf_system_shutdown().  Commenting-out pmf_system_shutdown() in
doshutdownhooks() does indeed appear to fix the reboot issue.  I'm not
sure if there are any side effects in doing this vs letting SRM fully
reinitialize everything, but everything at least appears to work
correctly.  It isn't a huge deal for me as I keep serial consoles on
all of my alpha boxen, but I'm sure others would greatly appreciate it
:).

Thanks!
