 Ok, seems like my Mainboard (Asus M3A78-EM, BIOS Version 2003) is to blame
 and FreeBSD has similar issues with it (although FreeBSD 8 boots fine, even
 when the BIOS options are set to "Auto", see below)
 
 this is the FreeBSD PR that helped me booting NetBSD 5.1_RC1 amd64:
 amd64/127484: [timecounters] Drift problem with FreeBSD 7.0 and 7.1
 PRERELEASE -- http://www.FreeBSD.org/cgi/query-pr.cgi?pr=amd64/127484

 My ASUS board didn't have any such option, but it had some
 "Overclocking" option which was set to "Auto". I changed this to
 "Standard". The clock now runs about 20 times closer to reality,
 which is enough for ntpd to work.
 
 
 You can find said BIOS settings via
 
 Advanced -> JumperFree Configuration -> CPU/GPU/PCIE Overclocking
 
 Set them to "Manual" and NetBSD boots fine with ACPI on
 
 I hope this helps anyone with similar issues
