Subjectuseful ram on voodoo(2) cards?
Folks,

Strange thoughts which I'd be grateful if someone could clear up for me:

a) is the 8/12Mb of ram on a voodoo/voodoo2 card read/write-able? [I'd
guess it should be writeable, given the card's function - but is it
readable?]

b) If the answer to a) is 'yes'. Would it be possible to write a driver
which provided a /dev/voodooram file and permitted people to do:

mkswap /dev/voodooram
swapon /dev/voodooram

[Such a driver would presumably have to prevent simultaneous access to the
card for graphics purposes or we would have some funky displays whilst the
machine hosed itself.]

And a subsidary question: given a), is this idea insufficiently ambitious
and could/should such RAM be usable as real system memory, not just fast
swap?

regards,

jb
