I have had problems with this card before, because I need to use both openmosix kernel and mpx motherboards. If you have no such requirements it should work fine with the pti_st driver you can download from promise web pages, and vanilla kernel 2.4.19 or 2.4.20. Try checking out the link below and previous posts in this list about promise sx6000 (same drivers as sx4000, I think)
