Ironically, Microsoft offers a choice here.

In the registry (NT and W2K at least, don't know about XP:)

HKLM\SYSTEM\CurrentControlSet\Session Manager\Memory Management
        LargeSystemCache : REG_DWORD
                0: prefer application code over cached data
                1: prefer cached data

Also:

        DisablePagingExecutive : REG_DWORD
                1: don't allow kernel code to be paged out

        IOPageLockLimit : REG_DWORD
                controls the amount of memory that can be locked for I/O
