Something is trying to map the page at 1MB -- probably some user-space 
table-scanning program (for example, I know some versions of dmidecode 
run past the 1MB boundary).
Actually, if your machine is non-ACPI then it is probably the kernel's 
ACPI code. That has had a bug for ages where it ought to scan 
0xE0000-0xFFFFF, but actually scans 1MB from 0xE0000. That would get 
you the error you're seeing. :-) I submitted a patch once...
