[ion] 24352: - Un-optimize KeGetPcr and make it use fs:20h instead of hard-coding the 0xFF.... address, because someone decided that ROS should have a different KPCR address then NT. - This gets NTLDR working with ReactOS and I can boot all the way to MmInit1 (which fails due to missing KeMemoryMap & freeldr data). - Serial port output works with DPRINT1 as well ; -)

Log:
- Un-optimize KeGetPcr and make it use fs:20h instead of hard-coding the 0xFF.... address, because someone decided that ROS should have a different KPCR address then NT.
- This gets NTLDR working with ReactOS and I can boot all the way to MmInit1 (which fails due to missing KeMemoryMap & freeldr data).
- Serial port output works with DPRINT1 as well ;-)
