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.

	Enjoy,
	Amancio
