kernel build/install problems (modules directory)

[Robert Staudinger]

Hello, 

i'm trying to build the linux-source-2.6.10 kernel package on my machine
(ppc G3/600) using the following command: 
-----
$ fakeroot make-kpkg --append-to-version=rst --revision=1 kernel_image
--initrd
-----

The deb builds smoothly but install fails with the message:
-----
mostpress:/usr/src# dpkg -i kernel-image-2.6.10rst_1_powerpc.deb
Selecting previously deselected package kernel-image-2.6.10rst.
(Reading database ... 131864 files and directories currently installed.)

Failed to create initrd image.

The problem seem to be that the modules are installed into 
/lib/modules/2.6.10rstn (note the trailing 'n')

The trailing n also shows up in my version.h
-----
mostpress:/usr/src# cat linux-source-2.6.10/include/linux/version.h
#define UTS_RELEASE "2.6.10rstn"
#define LINUX_VERSION_CODE 132618
#define KERNEL_VERSION(a,b,c) (((a) << 16) + ((b) << 8) + (c))
mostpress:/usr/src#

I'd be very happy for any hints.
Thanks, 
Rob
