[Bug 52284] Battery reporting only works after switching to an external monitor during Grub

[Frank Murphy]

Public bug reported:

Binary package hint: linux-image-2.6.15-25-686

Really.

I have a Toshiba Satellite M25XS149 and it seems to me that the battery
detection worked great in Breezy, but I don't totally remember. But for
a few months it hasn't worked. I discovered that it would work if I
tried to switch the monitor output to an external screen (with fn+F5)
during the grub screen. With a TV attached to the S-Video or with no
screen attached, the /proc/acpi/battery/BAT1/* have contents. (And seem
to work great.)

If I don't do this, it seems that the battery is detected, and if I
check right away, even found. But after the first file access, it
doesn't work any more.

I tried adding ec_burst=1 to the menu.lst, to no avail.

I'll attache the relevant dmesg output soon.
