IIRC, wasn't the bug more to do with the alpha formats of DXT? DXT1 has 1 bit alpha, DXT3 has uncompressed alpha, and DXT5 has compressed alpha.
DXT5 looks the best with alpha gradients, as more info can be stored in the compressed 4bits, than uncompressed 4bits.
You are right, though look at Quake3 qith DXT1 TC enabled in Linux and you will see it looks much better than it does in Windows 9x/NT.
On the last set of message boards there was a massive thread about it.
