I built a 2.6.24 kernel with the crypto stuff built in the kernel instead of
modules. To do that, in linux-rp-2.6.24/defconfig-c7x0 (from the stable
branch) I changed CONFIG_CRYPTO_ALGAPI, CONFIG_CRYPTO_ARC4 and
CONFIG_CRYPTO_MICHAEL_MIC to "y".  With this kernel, and after removing
relevant kernel-module packages (they seem to conflict with the in-kernel
crypto stuff), WPA works!

Note: I built and flashed many kernels with different options for the crypto
modules and it is well past midnight here, but I am pretty sure that the above
is the winning combination. Hopefully this may give an idea to Angstrom
developers about the solution.
(I have to mention it: OE is incredible - a new kernel is only a "bitbake
virtual/kernel" and a few minutes away).
