I agree with u, 
if there are holes and all in the area being scanned also with this fail ?

anyways, how can u get this from processor also ? 
I vaguely remember see'ing some code where someone on a i386 based
plattform but WITHOUT bios, used smbus protocol to talk to a device
across PIIX4 to get the info.

I am not familiar with PC architecture, so can someone tell me if
there is some standard chip  (memory controller? ?) where one can read
this on PC type arch. atleast ?

I am on  a IXDP425 plattform, and so far I cannot see any such
register on the data sheets ..
