WPA-PSK on Thinkpad T40

Not true. There are numerous config examples which feature hex psk,
but they are longer. If I provide a random hex psk in 63 characters,
it accepts it.

The problem is that my psk is 26 characters, and this works with other
operating systems, so I don't understand why wpa_supplicant should be
rejecting it.
