One advantage I can think of off the top of my head is that a lot of these fakeraid controllers have a limited BIOS that allows you to boot from a RAID-0 (or RAID-5 if they support that configuration). With Linux MD RAID you can, AFAIK, only boot from RAID-1, though you could of course have a small /boot on RAID-1 and have the rest on RAID-5, or have /boot on one disk, swap on the other, and the rest a big RAID-0. Fakeraid would also be an advantage if you want to dual boot with Windows, unless somebody invented a Linux MD RAID driver for Windows without telling me.. (dual booting is probably a bit unlikely for a server, though :) If you really want to use fakeraid on Linux (perhaps just to try it out for hack value) there is dmraid[1], which uses the device mapper to support the RAID layout of various fakeraid cards. I've never tried it myself, however, so I can't really say much about it apart from the fact that it exists.
