We have inb and outb. Can't vmware be written in Forth? If inl cannot be
replaced with inb, I'd rather add inl than vmware.

IMHO, it would be better to add

exec="include /boot/vmware.4th"

to the end of your /boot/loader.conf, and either execute vmware-conf
from there or script the whole thing:

s" arch-i386" environment? [if]
        \ Get vmware version, magic
        0x564d868 ( VMware magic ) = [if]
                .( VMware version ) . cr
                .( Loading /boot/vmware.conf...) cr
                s" /boot/vmware.conf" read-conf

Either way, no changes to /boot/loader.rc would be required.

        Hmmm - I have to go check this. My reality assumptions are shattered.
