Dunno, I've never done it any other way. I just figured since I was
compiling from source anyways, I would set the appropriate arch.

I started with Debian sarge. Trying to work through my tv out problems,
I switched to a self compiled Xorg, and not being a deb wizard, I then
had to compile everything that depended on X. I'm sure if I took the
time, I could have found a deb for Xorg 6.8.2, and learned how to use
deb sources so I could do the unichrome patches. Or even just found
unichrome debs. But even though it has been frustrating, sometimes I
like to build the stuff myself so I know more about how it works.

I never installed longhaul, and I've never had DMA issues. I'm just
referring to the constant stream of via dma complaints, system lockups
I believe. I imagine you could be right, that longhaul has a large part
in it. Also, I know the ivtv people recently discovered they had been
letting a bad default value exist for dma timeouts, and this somehow
affected via more than other chipsets (via chipsets had a different
default dma timeout value?).
But, since I don't seem to have any dma issues, I'm just worrying about
the problems I do have. I'm thinking .18 will fix my XvMC VLD, and then
I need to find a job, so I can pay someone to come and tune up my TV!
