perhaps an update would help as the current xorg for sid is 1:7.3+17[1]. 
Furthermore I am running a multi seat environment with this server w/o 
problems using a PCI- and an AGP-card(*).

You are obviously referring to PCI devices so I cannot see a reason 
other then hard to find violation of syntax ;-) for the server to 
complain, but that is perhaps my problem :-)

For a test would you just drop the -isolateDevice statements from the 
*dm.conf lines and try the BusID statement in the respective "Device" 
sections of your xorg.conf? For instance something like

Section "Device"
	Identifier	"Foo"
	Driver		"somedriver"
	BusID		"PCI:1:0:0"

Section "Device"
	Identifier	"Bar"
	Driver		"someotherdriver"
	BusID		"PCI:0:8:0"

Have fun & good luck :-) Alexander.

(*)I am using a third, dummy X server to initialise all the stuff but I 
don't know whether this is really necessary.
