So it seems it is not honoring our writes to the command register to turn on
I/O or memory decoding.
Oh weird, in your last case it seems they are enabled. (Driver not loaded at
all). Wonder if something in the driver startup is stomping on the PCI
command register (e.g. in the firmware).
Might be interesting to add printfs in re_attach() and see when the relevant
bits in the command register change (e.g. do they get turned off by
re_reset()).
