Hi, all,
	Inverted rotation issue (icon and glyph missing and desktop Corruption phenomenon), it was tested by Frank and Mitch, also I have made a lot of testing (e g: change the Graphic memory in BIOS, long time to do the inverted rotation and then click the icon/button, change the display resolution, open the website, the Patch has supported x-server 1.6/1.7/1.8/1.9, running on ubuntu 10.04 and Fedora 12 platform etc), the feedback is well.
	About this patch, since the scratch pixmap header will be re-used after allocation, we need to clear its buffer object attachment when we stop using it, otherwise a later user will use a bogus buffer object. In addition, the pitch values also need to recalculate in lx_crtc_mode_set function, it is a line size, otherwise, the desktop will occur corruption.
	The commit is on http://cgit.freedesktop.org/xorg/driver/xf86-video-geode/commit/?id=74e28b83d5b725a134aad264771a7c9a4d0e38df , any feedback, please told me.
	It is focus on Ubuntu Bugzilla #377929 & Debian Bugzilla #512020.

Thanks,
Hunk Cui
