Kernel Version 2.6.15 in any Fedora Version ?

[G]

Hi

Has Fedora shipped the 2.6.15 series of kernel by default ? I checked
FC4 and FC5. FC4 by default uses 2.6.11 and FC5 uses 2.6.16. For some
development and testing purposes i need 2.6.15 so can i load FC4 and
download kernel 2.6.15 from kernel.org and compile it ? I feel
upgradation is better than downgrading (i.e, by installing FC5 and
then downgrading to 2.6.15)

Please let me know

Thanks,
Regards,
