The wlan driver module will not be loaded when you boot the eeepc with
wlan off, because the device is non-existent for the kernel, similar to
an not plugged PCMCIA card. Without the pciehp module lodaed it will not
be detected, when you activate WLAN useing the the hotkey. Even when you
boot your eeepc with WLAN turned on, WLAN will work only after boot, not
after turning it off and on again, or after suspend/hibernate. There are
scripts which help to fix these issues, but force loading the pciehp
module simpliy makes it work. Suspend and hibernate need no script at
all and for the WLAN-hotkey, you need a script for kernels before 2.6.28
only, that simply switches WLAN on and of via /proc interface.
