If you wish to verify the integrity of a downloaded kernel before installing it, we've accommodated you by providing MD5 checksums with each build. You can verify downloaded kernels with a simple command. First verify that you've downloaded the kernel and the accompanying md5 file, then check them using the md5sum command. In this example, I'll verify the i586 kernel:
md5sum -c i586.md5
The results should look as follows:
linux-headers-2.6.29.4.i586.hwf.01_2.6.29.4.i586.hwf.01_i386.deb: OK linux-image-2.6.29.4.i586.hwf.01_2.6.29.4.i586.hwf.01_i386.deb: OK
