As  recently reminded myself by accidently mixing up motherboards and 
getting a silicon image based SATA board those companies chipsets are to 
be avoided at all costs.

There are currently 3 chipsets that I would recommend.

Promise SATA (non RAID like the SATA TX4 and SATAII TX4)
AHCI based chipsets (like Intels later chipsets which have published 
3ware SATA boards (8000, 9000 series) which have had drivers for a long 
time, these are "hardware raid" cards

I have used promose and 3ware, and according to the libata docs the 
Intel stuff is good, if it is the new stuff. Older stuff is not so good.
