You are correct. The underscore hack works with IE 5 and 6 only.
An extension of this is to use an asterisk instead of an underscore
to hack for IE7 as well. Obviously you don't need that, but I mention
it for completeness.
FWIW - I use these hacks while fixing up IE oddities during development.
I think it preferable to use another technique for the final cut, though.
Something like the one Manny Blum suggests looks good.
Also perhaps relevant, or perhaps not -- you can combine GIF-like
binary transparency with alpha transparency in a single 8-bit PNG.[1][2]
Not so good if you really do need more colors, but an alternative.
