Thanks for the fast response. I just need a little more info.

The only video related module I was explicitly loading was bttv in 
my /etc/modprobe.preload. There was a line in /etc/modprobe.conf:

options bttv vbibufs=32 gbuffers=32

that I changed to:

options bttv vbibufs=32 gbuffers=32 card=15

and rebooted, but that didn't help. So I tried the following to see which bttv 
related modules were loaded:

[root at rldt01 ~]# lsmod|grep bt
bttv                  148944  0
video_buf              17092  1 bttv
firmware_class          7424  1 bttv
i2c_algo_bit            8488  1 bttv
v4l2_common             4640  1 bttv
btcx_risc               3912  1 bttv
tveeprom               11512  1 bttv
i2c_core               17360  5 nvidia,tvaudio,bttv,i2c_algo_bit,tveeprom
videodev                7104  1 bttv

Then I tried the following to see which modules were available for loading:

[root at rldt01 ~]# find /lib/modules/2.6.12-22mdk/kernel/ -name "bt*" -print
/lib/modules/2.6.12-22mdk/kernel/3rdparty/dxr3/bt865.ko.gz

/lib/modules/2.6.12-22mdk/kernel/drivers/media/dvb/bt8xx/bt878.ko.gz
/lib/modules/2.6.12-22mdk/kernel/drivers/media/video/bt819.ko.gz
/lib/modules/2.6.12-22mdk/kernel/drivers/media/video/bt856.ko.gz
/lib/modules/2.6.12-22mdk/kernel/drivers/media/video/btcx-risc.ko.gz
/lib/modules/2.6.12-22mdk/kernel/drivers/media/video/bttv.ko.gz
/lib/modules/2.6.12-22mdk/kernel/sound/oss/btaudio.ko.gz

So if I had a bt878 chip, I could modprobe that module. But there is no 
corresponding module for bt848.

If it's any help, I also checked for bt related messages in 
my /var/log/syslog:

Do you think loading the bt878 module with the card=15 option would help? Is 
it possible that there is sufficient compatibility between them for it to 
work? 

Any other possibilities you can suggest?
