Looks like a very standard startup-sequence. Just to confirm, you have disabled user-startup and WBStartup with this ammended startup-sequence?
It might be worth booting with no startup-sequence and just running setpatch, let setpatch reboot the machine, boot with no s-s, run setpatch again, then once again launch the WHDLoad game from the CLI window. This will test whether Setpatch is causing problems with WHDLoad (can't see why, but it doesn't hurt to rule it out).
Finally, are you certain that the libraries for your accelerator are installed correctly?
