nope, currently not possible with unpatched linux/xfree :(
i've tried several times to submit a patch for inclusion
but i never got a reply :(

there are some talks about the future, but as i see it
it wont be any time soon, IIRC the last discussions 
could be find at dri-devel & fb-devel ml's

what now works (and maybe it's already for 2 years)
could be solved by patching X and/or linux

so there are two issues 
(have in mind that this is (b)ruby POW,
 not speaking of Miguel way)

every new instance of X blocks PCI access for
all previous X instancies

this is addressed by patching X with the patch
from the bruby web page or the newer version
that's in debian's xfree

or mandrake's (applies to xorg-6.8.1

the kernel(having linux in mind) treats all keyboards
as a single input keyboard
(b)ruby patched linux treats independand keyboards 
as independand devices

that's not developer POW, 
i'm just a ruby user
