Yes, Highpoint 37X is. See below.

_Not_ the 154x/1640, which is what John said this is.

Garzik has no driver for non-Marvell-based Highpoint cards -- so one
ends up either using the proprietary vendor driver (I wouldn't) or the
standard drivers/ide set.

Well, not "out of luck": You use the drivers/ide set for generic block
device support, and then do RAID using the standard Linux "md" driver.
Or, if on 2.6 kernels, and _if_ the Highpoint chipset is of the 37X
series, you can use the dmraid successor to 2.4's ataraid architecture,
and be able to support Highpoint fakeraid directly.
