RE: Heads up: checking in change to ata-card.c

Nvidia (I previously didn't know they made full chipsets)
IDE interfaces got broken around FreeBSD 4.3 and at 4.8 they are still
not working.. There is however a workaround which is to disable the use
of DMA on the devices (in the loader.conf file). if you don't the system
hangs during boot.

I have only sporadic access to one, but I don't have one myself which
makes it hard to
test more..
I have not tested it on 5.x yet..

I can get correct model numbers, etc. if helpful. This is a 4.8-RELEASE installation. I had to reboot the first time with an old 4.4 GENERIC leftover from installation, and I saw no errors, but after compiling a uniprocessor kernel I started seeing the above behavior. Although, I left it for awhile and eventually the machine does boot after about 30 of the MODE_SENSE_BIG, resetting devices lines.
