Here is the lspci-vvv from the PCI Bridge:
00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 82)  
(prog-if 00 [Normal decode])
	Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr-  
Stepping- SERR+ FastB2B-
	Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort-  
<TAbort- <MAbort- >SERR- <PERR+
	Latency: 0
	Bus: primary=00, secondary=01, subordinate=01, sec-latency=64
	I/O behind bridge: 0000c000-0000cfff
	Memory behind bridge: ff700000-ff7fffff
	Prefetchable memory behind bridge: fff00000-000fffff
	Secondary status: 66MHz- FastB2B+ ParErr- DEVSEL=medium >TAbort-  
<TAbort- <MAbort+ <SERR- <PERR-
	BridgeCtl: Parity- SERR+ NoISA+ VGA- MAbort- >Reset- FastB2B-

It does not appear to have any parity error checking enabled.
Here is lspci -xxx:
