Or if you have this installed:
http://timeless.justdave.net/maemo/repository-maemo-org-dns-0.1.deb
Then these urls
http://mxr.maemo.org/os2008/search?string=light%20sensor&find=kernel-&
http://mxr.maemo.org/os2008/search?string=light%20sensor&find=hal-&

Of interest is probably this:

2.6.21.0/debian/changelog#361
 361   * I2C: TSL2563 Light sensor integration time fix

Which shows that the i2c TSL2563 thing is Nokia related

Googling for i2c and TSL2563 should probably get you the rest of the
