Thanks anyway, and if you are still interested, I have found one solution
(or workaround).

(I am also CCing this to Sun in case they can shed any light on this often
reported problem)

In the jre\lib directory there is a file named rt.jar
Make a copy of it, rename it to rt.zip, then use WinZip to remove the file
KeyTool.class
Then run it using java. You have to specify the package. For instance:

java sun.security.tools.KeyTool -genkey -keyalg RSA -keysize 1024 (whatever
other params...)

This seems to work, even though:

keytool -genkey -keyalg RSA -keysize 1024 (same other params...)

always fails with "KeyPairGenerator not available"
