Did you try swapping the PCI cards around? The IRQ routing for the noname 
board has a flaw in that it assigns the nonexistent IRQ13 to one of the PCI
irqs. 

I use this patch on my noname for months:


diff -ur linux-2.4.0-prerelease/arch/alpha/kernel/sys_sio.c linux-2.4.0-prerelease-work/arch/alpha/kernel/sys_sio.c

+		route_tab:	0x0b0e0e0e,
 	}}
 };
 ALIAS_MV(noname)


But note: This maps 3 of the PCI irq's to IRQ14 that is only available if you
don't use IDE. (I never tested IDE. maybe it even works) The Problem in the
route_tab above is the '0d' (==13). Set it to anythig not used by ISA-Cards.
Sharing with other PCI cards is allowed.
Another save option might be 0x0b0a0f0f.

The 3c905B and my ISDN AVM Fritz!PCI work just fine here.

Bye,
Thorsten
