Yes. 
MAX_PAGE_SIZE is a system define in NT/XP. It's been 4K (4096 bytes)
since day one; it's unlikely to change in the IA32 world. MAX_PAGE_SIZE
is also the maximum size of physically contiguous memory you should
count on for a WindowsNT/XP system. To use larger amounts of memeory,
your PCI card needs to have its own page table system.
