Looking around on the net and FreeBSD archives it looks like if you want 
cheap ATA Raid now go with either a Intel motherboard with ICH5 or 
Promise SATA TX2/TX4
The performance of the Intel ICH5 looks very good with low CPU 
utilization (well from what benchmarks in running from MS windows suggest)
I haven't found any clear documentation on what can and cant be used.
