Debian seems to have some unique problems in the way they handle AMD64 compared to other distributions. I would not trust what you read there, they make it much more complicated than it really is. The right forum would have been discuss@x86-64.org

It's that way. You just need a 64bit capable cross compiler to compile the kernel, which is not that difficult to build from sources. You can also find binaries for that at ftp://ftp.suse.com/pub/suse/x86_64/supplementary/CrossTools/8.1-i386/ (usable with rpm2cpio on non RPM distributions). Then you can cross compile the kernel in the normal way with make ARCH=x86_64 CROSS_COMPILE=x86_64-linux-
A few programs (namely iptables and ipsec tools) need to be used as 64bit programs because the 32bit emulation doesn't work for them. ipchains works though.

2.4.25 supports 64bit just fine.
