eda28b95f4 unfortunately this change is rquired to make SMAP and SMEP features to work. 
I observed ~5% emulation slowdown ... thinking about possible mitigations

this fixes TLB issue with SMAP and SMEP features.
these features introduce a new behavior when page can be inaccessible by System (CPL=0).
Current behavior is accessBits was not supporting it but legacy (from Bochs 2.3.6) was.
The wrong behavior can be observed if user access a user page and system access the same page later.
user access is fine and pass SMEP/SMA checks and stores the translation in TLB.
the system access will hit the TLB and nobody could detect that system cannot access that page.

cc56245407 started implementing the i430FX chipset 
- renamed config parameter "i440fx_support" to "enabled"
- new config parameter "chipset" added (current choices "i430FX" and "i440FX")
- don't load ACPI support if the i430FX chipset is selected
- select register values for the core PCI devices depending on the chipset
- USB UHCI must be connected to a PCI slot if the i430FX chipset is used
- rombios changes to make the i430FX chipset work
- TODO #1: implement limitation to 1 cpu and 128 MB RAM for the i430FX chipset
- TODO #2: verify register behaviour of both chipsets
