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
