scsi card compatibility under Debian

[Mark Seven Smith <pampaluz@home.com>]

I'm trying to get a scsi card (for an old HP ScanJet 4p 
scanner), though eBay; and in trying to determine if a card 
advertised will work with Linux, I went to the Debian 
homepage, and was told that Debian has no hardware 
requirements beyond those that come with Linux.  Then there 
was a link to check the hardware compatibility HOWTO.  But 
the HOWTO doesn't list scsi cards!  In fact, I couldn't 
find a list of any scsi card compatibilities, except in 
doing a search from Google, I came across the hardware 
compatibility lists for Red Hat Linux--they list all the 
hardware that they *CERTIFY* to run with Red Hat Linux, and 
what version of RHL each card or whatever works with, which 
isn't much helpful for Debian stuff (unless I could get a 
particular scsi driver from a Red Hat site, if that is what 
they did to make that card "certifiable").

Does anyone know of a place that I can check for the 
compatibility of a particular scsi card, especially for 
Debian?

TIA,
