I hope you don't mind my e-mailing yor directly. Did you get the Promise SATA150/Fastrack 378 S-ATA controller driver working with Fedora on the ASUS P4C800-E motherboard?
Not a problem at all!
I did get it working after _much_ fiddling around. I had to build a driver disk though, and every time a kernel update comes out I have to manually rebuild the module and the initial ramdisk.
I wish I would have documented it a little better, cause I've sort of forgotten. I could probably get you an img of the boot floppy I made if you're interested.
