If you just need to expand your Mainboard with a SATA Controller, all you need is a poor card with a Silicon chip on it (Sil 3112 etc). I've seen cards starting at 10$. Almost all low-cost cards have this chip series, meanwhile on 5.3 it should work now without any problems. The WRITE_DMA issues should be solved and commited to 5.3.

Unless something happened in the past week or so, you can still have WRITE_DMA problems with the SiL 3112 if you connect a "fake SATA" drive to it, such as some of the Western Digital drives. These are really ATA drives with a little conversion-chip on them to implement SATA. These drives seem to work okay on more expensive SATA controllers, but I had a *lot* of headaches with one connected to a SiL-3112 controller. I suspect that the same people who are willing to live with a $10 disk controller are also going to be tempted to buy the less-expensive "fake-SATA" hard drives...

Have also a look at the 5.3 hardware list: http://www.freebsd.org/releases/5.3R/hardware-i386.html#DISK.
