This patch didn't take correctly here, so I applied it manually and
created another patch.
(I can boot as far as "Northbridge prior to SDRAM init:" and then I
still get random hangs about this point. Patch doesn't seem to break
anything here. Since I'm hacking on my DFI P2XBL w/ w83977tf, I can't
easily test on my Tyan S1832DL with S1846 profile right now.)

Fixed a bug within the 440bx RAM size calculation. Since the DRB values
on the 440bx are 8MB units we need to shift left by 13 to get it into kb.
