Can I use it to mine Skein or Qubit algorithms on a 32bit Windows?
Sure! Here's a quick cut 'n' paste from the /help. These algos supported.
scrypt scrypt(1024, 1, 1) (default)
scrypt:N scrypt(N, 1, 1)
sha256d SHA-256d
blake Blake
cryptonight CryptoNight
fresh Fresh
heavy Heavy
keccak Keccak
lyra2 Lyra2RE
neoscrypt NeoScrypt(128, 2, 1)
nist5 Nist5
pentablake Pentablake
quark Quark
qubit Qubit
shavite3 Shavite3
skein Skein
s3 S3
x11 X11
x13 X13
x14 X14
x15 X15
Edit: WHUPS!!!! That's not this cpu-miner, that's THIS cpu-miner...
