icotool's --help is confusing.  The magic incantation is:

	$ icotool -c -o cygwin-term.ico -r cygwin-term.png

where cygwin-term.png is the 256 px Vista icon.  -r is the trick.  You 
then append the PNG files for the smaller sizes to the list to have them 
translated to BMP style "standard" icons within the aggregate .ico.

.ico is originally based on BMP, which is a trivial uncompressed file 
format, basically a small header containing obvious things like width, 
height, color depth, pixel format and such, followed by raw pixel data.

So, a 32 bit RGBA 256x256 .bmp or .ico will be 262,144 bytes plus header 
overhead.  (I get 270,398 bytes here.)  Your 300K+ file probably got a 
bit bigger due to having more icon sizes bundled in.

I use the ICO file plugin for Photoshop from Telegraphics, the same 
people that put out icobundl.  You get a dialog on saving the icon, 
asking if you want a standard or Vista PNG .ico; I say Vista for the 256 
px one, and standard for the smaller four sizes.  Then, I use icobundl 
to take the resulting 5 .ico files and assemble them.

I can do final compression and assembly if you need me to, but I think 
the icotool incantation will fix your problem.
