I found a workaround: Use "mem=2048M" (I will try higher values) as a boot option! That way the SATA /dev/sda is correctly detected and I can use it under X86_64 (as I already could under plain X86 / i386). Apparently my 4GB RAM is causing the problem.
I got this workaround from the thread http://www.mail-archive.com/[EMAIL PROTECTED]/msg06174.html . http://www.mail-archive.com/[EMAIL PROTECTED]/msg06310.html has a patch, I believe for 2.6.22, so not suitable for my 2.6.20.
