[sir_richard] 45519: [FREELDR]: The WinLDR code forgot to update the File Path of boot driver entries from PA to VA as well, not just the registry path. It also tried to touch the PA LoaderBlock right after enabling the MMU. It should touch the VA LoaderBlock instead, since there is no guarantee that the address has been identity mapped (and hence the PA address interpreted as a VA address by the MMU is bogus).

[sir_richard] 45513: [NTOS]: Make system startup match x86 code as closely as possible, instead of mixing MIPS/PPC code. Only rip out parts that are obviously x86-specific. Also fix code to use new KPCR definitions. [NTOS]: Implement a DbgPrintEarly function that directly uses KDCOM to print to the serial console, instead of going through the Debug Service Interrupt.
