intell i830 and kernel 2.4.19

[Arash Bijanzadeh <a.bijanzadeh@linuxiran.org>]

I have got a Inspiron 2600 Dell laptop. It has a i830 Intel VGA 
card with shared memory that's  so i have to use kernel-image 2.4.19 that's 
the only wersion which supports it. Firstly i compiled it from a fresh source 
that I have got from kernel.org it didn't work complaining that she couldn't 
mount the root ?!After that I installed kernel-2.4.19-386 from testing 
distrib by apt-get. Now it can boot the system, but it complaining that the 
root filesystem is readonly so it can't write the log file and such a things, 
and worst tat that it couldn't run modprobe, so I missed every module on it. 
I think the problem is with initrd.img.
Can anybody help me please to librate my  laptop ?
Thanks a lot Arash
