Vitesse VSC7250 (Promise EX6850) SAS/SATA controller unsupported in 8?

[Bill Desjardins]

Hi All,

I have an Arima NM46X motherboard with a built-in Vitesse VSC 7250 SAS
controller which appears to be a rebranded Promise EX8650 from what
little information I could dig up. During POST all 8 drives are seen
but freebsd cant see them. I've tried JBOD and RAID configurations,
but nothing. I found that the last driver offered by promise is a
kernel module, stex.ko, but it is for 7.1. is there any new driver for
this or am i SOL? If this is something that someone could fix, I can
easily provide a complete remote environment with console access.

Some relative info: (let me know if you need more)
