dri from chroot

[Filippo Carone <f.carone@fastwebnet.it>]

 Hi everybody,
 I installed the chroot to run 32bit apps, but I'm not able to access
the /dev/dri/card0 file either binding /dev on /chroot/dev or creating
/chroot/dev/dri/card0 . stracing on glxinfo inside the chroot or by
dchroot:

stat64("/dev/dri/card0", {st_mode=S_IFCHR|0666, st_rdev=mak
edev(226, 0), ...}) = 0
open("/dev/dri/card0", O_RDWR)          = 4
ioctl(4, DECODER_GET_CAPABILITIES, 0xffffd8c0) = -1 EINVAL (Invalid argument)

so the DECODER_GET_CAPABILITIES ioctl fails. Of course outside the
chroot this doesn't happen.

 Any hints?
