Pentax K into Canon adapter not available?

I've googled both on the web and the groups and have come to the
conclusion that I will not be able to get an adapter to allow me to
use my old Pentax "K" mount lenses on my new Canon EOS 300D (that's
Rebel to my American friends). I'm hoping that someone knows better,
otherwise I'll have to start saving.

My Pentax lenses are totally manual so preservation of autofocus is
not important. It's just that I've a 135mm lens that would make a
lovely medium-length telephoto on the Canon, just right for sports
photos.
