I have a netbook (Acer Aspire One A110L) and installed a 1GB DDR2 in the
available slot, for a total of 1.5GB or RAM.
The BIOS reports it as 1.5GB and so does grml linux (booting from usb),
but the installed gentoo linux reports only 904600 kB:

I suspect it has to do with my kernel (2.6.32-gentoo-r1) configuration,
but do not know where to look.
Any suggestions ?
