Yes. I was also facing similar issue. This workaround works for me. Tested using lenovo R61.
so you're saying that you were persistently getting a black screen boot, but that that simple tweak solved the problem? i'm not scared to admit that i still don't understand *how* that fixes things, i was just following the guidance of the appropriate mailing list and, so far, things have been working. i'm sure there will be a formal fix in the near future.
Yes. I was getting black screen consistently. I do not remember exactly from which version issue started happening. But behavior was different with different kernel version. In 2.6.37 I used to get scrambled output. In 2.6.38-rc2 I get black screen, but CAPSLOCK LED is blinking continuously, probably a kernel panic. With this workaround I get the desktop.
