No, the p1020rdb and p2020rdb do not have the IDSEL entries:
http://lxr.linux.no/#linux+v2.6.38/arch/powerpc/boot/dts/p2020rdb.dts
whereas the p2020ds has:
http://lxr.linux.no/#linux+v2.6.38/arch/powerpc/boot/dts/p2020ds.dts
What would the correct IDSEL entries be?
Also, did you see the reference to Felix' thread?
"Problem with mini-PCI-E slot on P2020RDB"
Best regards,
Leon.
