custom kernel revision `make-kpkg`

weedlight

Hi, I compiled a custom patched kernel on debian stable with `make-kpkg` but when I tried to install it on my unstable installation it complained that version number doesn't start with a digit. Now, I'm compiling it without the "--revision" parameter, but I'd really like to use this parameter.

I run `make-kpkg --initrd --revision=weedlightRT.1.0 kernel-image` on the stable installation and on unstable `dpkg -i ../linux-image-2.6.33.9-rt31_weedlightRT.1.0_amd64.deb`. And here is the output given:

dpkg: warning: parsing file '/var/lib/dpkg/status' near line 45303 package 'linux-image-2.6.33.7-rt29':
