For the record, I had nothing to do with identifying the problem
or recommending a solution. The algorithm is pretty simple:
....
old_checksum = page->pag_checksum;
page->pag_checksum = 0;
p = (ULONG*) page;
checksum = 0;

do
{
checksum += *p++;
checksum += *p++;
checksum += *p++;
checksum += *p++;
checksum += *p++;
checksum += *p++;
checksum += *p++;
checksum += *p++;
}
while (p < end);

page->pag_checksum = old_checksum;
....
