(BWell, one question might be how fast you need it to be. Another, of
(Bcourse, is how the time spent trying to bring it up and the education
(Bgained thereby would compare with just requisitioning a card for the
(Bborked motherboard. Yet another question could be how much the lab wants
(Bto invest on a slow motherboard with broken curcuitry (which might also
(Bdepend on what borked the on-board ATA controller). 
(B
(BATA controllers can be pretty cheap, particularly if you don't need to
(Bboot from them or build raid on them. Motherboards aren't necessarily
(Ball that expensive, either, especially if the application doesn't demand
(Bfast response.

(BIf you do buy a controller, check the hardware compatibility list and
(Balso check that the board works with a slow, older motherboard.
(B
(BMy impression is that support for some boards is not compiled in, so you
(Bmay be faced with compiling your own kernel. (If I understand the
(Bhandbook correctly.) 
(B
(BI am faced with exactly this question, but I have a lot of other
(Bproblems with higher priority, so I've been dodging it.
