+- commit message if execution of code in IO memory
+- update doc: PCI infos.
+- VNC patch + Synaptic patch.
+- basic VGA optimizations
+- physical memory cache (reduce qemu-fast address space size to about 32 MB)
+- better code fetch (different exception handling + CS.limit support)
+- do not resize vga if invalid size.
