They never start working in current git version.

Lot more problems as well, now that I am testing with 2.6.24.7:

* If I type:

cd /sys/mod

and hit tab for the completion, I hear nothing, even though the word 
"modules" completes.

* Same if I type "spe" tab, to get "speakup" after that.

* Shell prompts are spoken if I press enter, and the results of echo are 
spoken ("echo this is a test." has "this is a test" spoken).
However, if in, for example, /sys/module/speakup, and I type "ls" enter, 
where I should here "parameter/", I hear nothing, not even the shell 
prompt.

* Random seeming other commands behave the same way.  If I type "sudo 
bash" to get a root bash, I hear nothing spoken, even though review read 
current line, after a suitable half second delay, will read "root at thor:~#" 
as it is supposed to have done before.  Typing "exit" from there, will 
return me to "luked at thor:~#", which is read.

* Running "less /var/log/kern.log" gets me no output, except in review.

* Testing with 2.6.24.7, now all key echo has the same delay as only 
review keys had on 2.6.18 with current git speakup.

Have done (2.6.24.7), and not only do they still happen, they are worse.

I will send you and Samuel, off list, a tar file containing a bunch of 
data: a kern.log sample, the kernel config, the contents of the speakup 
parameter directory while this is all happening, etc.

Similar to the way in which one can loop mount an iso file, one can use, 
for example, the "cryptmount" package, to create encrypted files, which 
can be mounted as normal loop file systems, and accessed on the fly, 
remaining encrypted for all storage.  I believe it uses the md_crypto 
module, which wasn't compiling properly for me in 2.6.24.7.

That is probably a kernel config issue.

I am going to try the pre-flush-changes version of speakup with 2.6.24.7 
using the same config, and see what my results are.
