knoppix-installer in 3.7 works from kernel 2.4.27(not 2.6.9)

I found this by 'trial & error' ; I have not found it posted before so this may help somebody else to save their time .

If running the 3.7 Live CD with kernel 2.6.9, and then doing sudo knoppix-installer, the installation seems to proceed OK, but then the installed system is not bootable. :?
However, if you boot-up the Live CD with the (default) 2.4.27 kernel, then all is well. :)
... and when booting the Knoppix installed on the hard drive (I install for the 'Debian' mode), then either kernel can be successfully chosen. :D
