This is an informational post regarding the eeepc_laptop - handling of
wlan using the rt22860sta - module on the eee1000

Adamm, using "echo 1/0 > /sys/class/rfkill/rfkill0/state is currently
exhibiting the same or similar errors with pciehp that were present in
eeepc-control 1.3.3 on hardy.

loading pciehp with "pciehp pciehp_poll_mode=1" in /etc/modules causes
the system to hard-crash immediately upon echoing 0 or 1 to .../state,
just like the original acpi-scripts did on eeepc-control 1.2.x (the ones
that were not rt2860sta-aware and did all its functions on the ath_pci -
module)

leaving the loading of pciehp out of /etc/modules (ie not calling it with pciehp_poll_mode, or perhaps pciehp_force) causes the machine to work, but the wireless will not properly load/unload, with the same kind of error messages:
...

Nov  5 12:16:19 minimeee kernel: [ 7765.663257] ERROR!!! BBP write R81=0xffffffff fail
...
etc ad nauseam

Interacting with rt2860sta (via network-manager, like trying to switch
AP's) while the module has been faulty unloaded like this will cause the
machine to hard-freeze again.
