[CentOS] OT raid controller

Sorry for an OT post, but given the recent discussions here re raid, I was wondering if anyone had any info on the ITE 8212 RAID controller (GigaRAID) This is a PATA HW RAID as found on the GigaByte GA-8I915P-PRO motherboard. (I can see an IC on the board labeled GigaRAID. Their manual claims that is has it's own CPU).

I am not using it because I have SATA, but I am still curious about it's HW v SW raid ability and general linux support. They do provide a linux driver but the install instructions refer to /dev/had (obviously a typo so I don't think it is well tested or supported).

I have tried google, but most references are to questions, now answers :(
