At the moment there isn't any stuff in the kernel to take care of changing the cpu speed a la cpufreq except Cesar's implementation on the debug branch. So kernel gets stuck with the clock situation that was handed to us by the bootloader -- the kernel doesn't "deal with" it at all. All it does is turn off charging if it sees it has 100mA USB connection, but it happily will try to turn on more than 500mW can deal with and die. We need to do more work in kernel to defer stuff like bringing backlight up (now it never comes up in bootloader) to meet the 500mW startup goal, so this isn't something to fix today on Qi. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkiq5jgACgkQOjLpvpq7dMqrKQCeJ8sNIiHibKNzrCTKUxTyYzel zgAAnRAoA0KpTiLiKu8LFEU0FIrG7eMe =WA36 -----END PGP SIGNATURE-----
