Yes, recent kernels disable device access once driver is unloaded:

mstflint -d 08:00.0 q
*** ERROR *** Read a corrupted device id (0xffff). Probably HW/PCI access
problem
*** ERROR *** Device type 65535 not supported.
*** ERROR *** Can not get flash type using device 08:00.0

mstflint should work without driver using /proc:
mstflint -d /proc/bus/pci/08/00.0 q
Image type:      Failsafe
I.S. Version:    1
Chip Revision:   A0


In gen1 flint had a separate driver which you had to load.
I am not sure whether this would work on 2.6.18

Probably not.
