Now you've got the Gentoo crowd double checking their linker man page... :)
Seriously, I've heard that the translation from a physical address to a particular bank/row/column combination is specific to the memory controller. Which makes perfect sense.
Also, let me make this clear: my bank comment was in regards to the "more details than you really need to know" section anyway. With Linux and/or random, commodity hardware, you can't call out a specific row or column either. But if you're going to talk about rows and columns, you ought to at least mention banks, the third address component of a modern DRAM. ("Modern DRAM" here means, approximately, anything I'm familiar with: Sync-DRAM, DDR, DDR2, etc.)
