I'm not sure what items you've read, but assuming that kernel is a direct
rebuild of the Red Hat Enterprise Linux 6.1 kernel of the same version,
those items are wrong. I know, because I wrote the patches that added the
v4l/dvb/rc backport from 2.6.38 to the 6.1 kernel. :)

Yes, the new rc-core in-kernel IR code, as well as the lirc compatibility
bridge and lirc_dev *are* provided in the 6.1 kernel. But no classic
lirc_foo device drivers -- those are still in drivers/staging/ in the
upstream kernel for a reason.

The above would work. As would building just lirc_zilog against the
kernel-provided lirc.h and lirc_dev.h, but that requires a bit of tinkering.
