Okay, I checked in a command-line option for Xen:
badpage=<page number>[,<page number>]*
Specify a list of pages not to be allocated for use
because they contain bad bytes. For example, if your
memory tester says that byte 0x12345678 is bad, you would
place 'badpage=0x12345' on Xen's command line (i.e., the
last three digits of the byte address are not included!).
