I like lower case more :)

I'd also put the bit number first and would align the columns, e.g
something like:

    bit  0: entry present		: true
    bit  1: read/write access allowed	: true
    bit  2: user access allowed		: true
    bit  3: page level write through	: false
    bit  4: page level cache disabled	: false
    bit  5: entry has been accessed	: true
    bit  7: page size			: false
    bit 11: restart to ordinary		: false
    bit 63: execute disable		: true
