It does not appear to be doing so. The version of 2.5.51 that I have is
the bitkeeper version that I grab via bk.=20

Here is the output of "make install" for agpart.ko:

Kernel: arch/i386/boot/bzImage is ready

I grepped for "remap_page_range" found
System.map:c0149bf0 T remap_page_range
System.map:c0413a40 R __ksymtab_remap_page_range
Binary file vmlinux matches

I found that in kernel/ksym.c at line 108 is the line that is suppose to
export the symbol:

EXPORT_SYMBOL(remap_page_range);
