And finally, after just resetting the bios, it looks right:

real memory  = 25769803776 (24576 MB)
avail memory = 24953413632 (23797 MB)

Which in itself is interesting. I reset the same after I had
changed the bios battery some time ago and didn't change anything.

So  whether or not the moving of the memory modules were necessary,
I don't know and I probably won't bother checking, at least for a
while, but it's a tip I'll look for the next time.

Thanks to everybody for your input.
