Could you try to add
	inl(ioaddr + SCBPointer);
	udelay(10);
before
	outb(RxAddrLoad, ioaddr + SCBCmd);
in speedo_resume()?

These two line are a workaround for the RxAddrLoad timing bug, developed by
Donald Becker.  wait_for_cmd_done timeouts may be related to this bug, too.

Well it now boots :)
I'll let you know if there are any more problems with it in use.

It always boots, with different rate of successive ones.
The question is how _often_ it boots successfully now :-)
