No. --------------------------------------------------^ Only as a swap file.

Yes. I've made it on 2.1.5.
1) configure your kernel with ``pseudo-device vn'', and boot it
2) mount your dos partition (of course, read-write ;-)
3) vnconfig -cs labels /dev/vn0 /your/path/to/386spart.par
4) disklabel -r -w /dev/vn0 auto
5) swapon /dev/vn0c
i) It's coming from my head (I made it on my home machine), so check for
typos, etc.
ii) the 2) is very dangerous as I know with pre-2.2 versions, if the DOS
partition was bigger with 1M and splitted with fips (or is bigger now!)
iii) the vnconfig's -s option isn't documented in my version, I found it in
the sources - maybe it has changed.
iv) the 4) point will give you warnings about incorrect pack label or
something - as I know, doesn't matter
v) As I know, you cannot ``swapoff', so you cannot umount your DOS disk
vi) as I know, windows will be screaming, that its swap file is corrupt or
something like this, so you have to recreate it in the next win-start-time.
VII) I HOPE IT WON'T MAKE ANY DAMAGE!
So, if somebody knows more about vnodes, or anything I have to know, please!

I THINK it's slower.
