FSO sources git version?

[Timo Drick]

Hi,

i have problems finding the right kernel sources that are used to build FSO

package called:
kernel - 2.6.24+gitr0+7a1370a816b9348dd8f36a667905dd3533cefc9b-r4 -

how can i checkout the sources of this kernel version?

git clone git://git.openmoko.org/git/kernel.git linux-2.6
git checkout 7a1370a816b9348dd8f36a667905dd3533cefc9b

returns:
error: pathspec '7a1370a816b9348dd8f36a667905dd3533cefc9b' did not match 
any file(s) known to git.

regards Timo
