this code is not responsible to initialize the cpu clock
it just read and calculate dynamicly the differenct at91 clocks

if this code does not work please not that linux will have the same problem
so please fix you lowlevel_init or your at91bootstrap

this crystal can even be detected by cpu without specify it

try without this define, by letting the cpu detect it
