I updated cvs yesterday (Aug 11, about 0:00 GMT), installed, and used my
standard trick:
prompt# ifdown wlan0; rmmod hostap_pci; rmmod hostap; rmmod
hostap_crypt; ifup wlan0
for hot reloading the wlan driver.
I am crazy enough to do this from a client connected through wlan0, and
it has always worked till now. The machine is a dual PentiumIII 1 GHz,
running:

I had to reset the machine after. the driver seems to be working nicely
since then.
I send this FWIW. The card has firmware 1.3.6, which I update (in RAM,
by hand) to 1.4.7 each time I reboot. When it hanged, then, it was
running 1.3.6
Regards, and thanks for the good work
