IMHO the patch makes it really hard to actually see what the code does.
I think Idwer was recently running into a problem where the use of
post_code would trash %eax were hard to comprehend. Now we seem have a
lot more code that comes from somewhere else and touches registers
without it being obvious to the reader of the code.

Uwe pointed me to this errata: http://www.intel.com/Assets/PDF/specupdate/253176.pdf

Is processor init (with or without CAR but preferably with) still possible ?

The CPU that's used on the board is either a "N = Intel ® Pentium ® 4 processor" or a "R = Intel ® Pentium ® 4 processor on 90 nm process", cpuid is 0xf29.

Just my 2ct.
