There was a new one just a bit ago, its now in a .inf file, instead of in the
driver itself. I believe someone updated the firmware versions page in the
ivtv wiki w/details...

Let me clarify why I said put the sbp2 module *and dependencies* in your
initrd. You can explicitly tell the initrd to load up the firewire card
drivers from there before loading the sbp2 module. Basically, just:
1) cp /boot/initrd-<kernel version>.img ~/
2) mv initrd-<kernel version>.img initrd-<kernel version>.img.gz
3) gunzip initrd-<kernel version>.img.gz
4) mkdir /mnt/initrd (or where ever else you like)
5) mount -o loop initrd-<kernel version>.img /mnt/initrd
6) cd /mnt/initd
7) cp /path/to/spb2.o lib/ (repeat for other modules)
8) vi linuxrc (add lines just like the ones in there to load up the modules
you just copied over)
10) umount /mnt/initrd
11) gzip initrd-<kernel version>.img
12) mv initrd-<kernel version>.img.gz /boot/initrd-<kernel version>.img
13) reboot, see what happens, rinse and repeat if necessary
I had to reboot a few times to get all the modules incorporated for loading
the PVR-350's frame-buffer from an initrd (so I could get rhgb on it), but
there shouldn't be quite as many dependent modules for sbp2. You might also
want to back up your original initrd while you're at it, just in case.

That'd require a lot less hacking. :-)
