Most definitely. Check out 'dmraid' too, which can setup devmapper to 
map disks to various $ODDBALL "proprietary" soft-raid disk formats, 
no idea whether highpoint is supported though.

Also, Jeff Garzik's libata has a WIP driver for some of the Marvell 
host controllers, which might be what the Highpoint uses. IME with 
sata_sil, even a beta driver from Jeff Garzik will be better quality 
than a vendor IDE/SCSI host driver (and improve far more rapidly).

See http://linux.yyz.us/sata/, particularly the HPT entry on the SATA 
status page:

 	http://linux.yyz.us/sata/sata-status.html#hpt

and obviously the marvell entry just above it. If your HPT doesnt use 
a Marvell, you're out of luck.
