No modifiedFlagsMask et.al access from python.
Also wouldn't it be better if the mask matches the actual flags bit positions?  
That way you may do bitwise ops with the actual EFLAGS register value. If not 
in C maybe in the py iface? 

r = {}
for i in range(0,0x100):
    CF = 1<<0
    PF =  1<<2
    AF =  1<<4
    ZF =  1<<6
    SF =  1<<7
    IF =  1<<9
    DF =  1<<10
    OF =  1<<11

    D_ZF = 1 # Zero */
    D_SF = 2 # Sign */
    D_CF = 4 # Carry */
    D_OF = 8 # Overflow */
    D_PF = 0x10 # Parity */
    D_AF = 0x20 # Auxilary */
    D_DF = 0x40 # Direction */
    D_IF = 0x80 # Interrupt */

    flags = 0;
    if i & D_ZF:
        flags |= ZF
    if i & D_SF:
        flags |= SF
    if i & D_CF:
        flags |= CF
    if i & D_OF:
        flags |= OF
    if i & D_PF:
        flags |= PF
    if i & D_AF:
        flags |= AF
    if i & D_DF:
        flags |= DF
    if i & D_IF:
        flags |= IF

    r[i] = flags
print repr(r)

Hey Felipe,
the reason I didn't do 1 to 1 map is because some flags exceed 8 bits 
representation and I'm cheap on memory.
However, for Python it might be convenient.
When I get the time I might add it, thanks.

Converted all the flags to be compatible with EFLAGS. You won't require a 
dictionary/lut anymore.
Thanks again, it was important IMO.
