Trouble with Asus SK8V MB with more than 2048M memory

I can't use more than 2048M of memory in my test machine.
The machine has AMD Athlon 64 FX with 4096 M of
physical RAM with Asus' SK8V Motherboard.
I use two 2048M modules, Kingston's KVR266X72RC25/2G.
I can't install FC5 x86-64 or any 64-bit Linux on the system without giving the parameter "linux mem=2048M" while installing.
If I give for example "linux mem=4096M" or no mem parameter the installation hangs allmost immediately. While launching installed system with bigger mem I have a kernel panic immediately.
The curious thing is that with Windows XP Professional x64-edition and 64-bit Sun Solaris the whole memory space is available. So there can't be any serious hardware or configuration problem in the machine.
Before touching to the hw configuration, I would like to understand the problem better. I have had the same problem with Gentoo, where I tried to solve this problem by recompiling the kernel. I was unable to solve the problem that way.
Has anybody been able to install Linux or FC5 x86-64 on that motherboard with more than 2048M of memory?
