Debian Etch (4.0) com Kernel 2.6.22?
Você compilou ou pegou do backports.org?

Baixei a versão 4.0 r1 para amd64 e fiz a instalação normal.

deb http://ftp.br.debian.org/debian/ lenny main contrib non-free
deb-src http://ftp.br.debian.org/debian/ lenny main contrib non-free

Depois via aptitude instalei o kernel 2.6.22-2-amd64
