Promise cards do suck somewhat -albeit I use them- but what else is there ? 
The highpoint-equipped cards are even more sucky in many cases.

Ehm, what ???  You're probably talking about the driver for the fasttrack 
cards who are -in their own respect- raid cards. But if you use a 'plain' 
card like the ultra it's just used as an additional IDE channel. That has 
worked long long before 2.4.20 and it is what I use.  No sense in buying a 
pricey fasttrack if you're not going to use the raid but use the md tools 
instead.
