The driver shall work okay with 2.2gamma. I am using 3.0-current. Download the driver from rah and read the readme file is very trivial to incorporate bt848 driver. How to install: In your kernel configuration file: device bktr0 In /sys/conf/files add: pci/brooktree848.c optional bktr device-driver Create the device: mknod /dev/bktr0 c 79 0 copy brooktree848.c and brktree_reg.h to /sys/pci recompile the kernel and make install after you reboot the driver is all set for you. -- A copy of grabber-meteor.cc is included in the distribution in case that you want to play with vic. "tv" you can download from my ftp site and just modify the entry for meteor0 to bktr0 and you are all set to watch tv 8) The only caveat here is that "tv" only works in 15bit, 32bit video modes. Luigi is supposed to have mods which allows "tv" to work in 256 colors. The video display's linear buffer vs paged buffer at this point will not affect the operation of the bt848 driver since it is not sending data directly to the frame buffer.
