I don't think PCI probing is at fault. You cannot disable probing
as this is a central piece of the resource management of the Xserver.
X doesn't deal with interrupts at all at the moment. Therefore I
doubt that this causes the trouble.

The X log file showes the same device on bus 5 appearing multiple times
under different function numbers. Ths device doesn't show up at all
in the lspci output. 
To me this device looks broken - however we may be missing something
in the Xserver code, too. Probing of PCI devices should not affect
these, though.
Please try to run 'scanpci -v' and check if this causes the same
problems.
