Sorry it has taken me so long to get back to you about the patch. I had a
lot of trouble compiling a kernel. I found that the 2.6.30 kernl won't boot
on my laptop. I tried the stock debian 2.6.30-486 kernel and tried
compiling one on my own. I was running a 2.6.26 kernel so I tried compiling
a 2.6.26 kernel but I couldn't patch in the screen reader (speakup). That
kernel booted but I wouldn't be able to tell if it had the pd6729 bug
because I can't access the console.
So I am now compileing a 2.6.29 kernel. The only problem is I cannot apply
the patch (rreproduced below). I cut it out of the email message and pasted
it into a file named pd6729.patch. I tried to apply the patch like this:
hutson:/usr/src/linux# patch -p1 </tmp/pd6729.patch
patching file drivers/pcmcia/pd6729.c
Hunk #1 FAILED at 641.
1 out of 1 hunk FAILED -- saving rejects to file drivers/pcmcia/pd6729.c.rej
I am thinking this means applying the patch did not work.
