Bug#472487: installationreport: low memory install lenny beta1: Problems
> 1. when trying to start graphical installer on a low memory system,
> fallback to text-based installer does not work, system hangs for
With 32MB internal memory, you're basically asking your system to do
something impossible: load an initrd that's almost the size of your memory
after a kernel has already been loaded.
Here are the _uncompressed_ sizes of the regular and graphical initrds:
-rw-r--r-- 1 fjp fjp 27515392 2008-03-31 10:58 initrd_gtk
-rw-r--r-- 1 fjp fjp 11127808 2008-03-31 10:59 initrd_newt
I suspect that the system is just running out of memory while loading the
initrd or very shortly after, with the kernel having insufficient memory
available even to handle the error.
If this is an issue, it's something in the kernel upstream as that is the
only thing that could detect the problem in a timely fashion and warn about
it. I'm not going to file a BR about it though.
Documentation seems the best solution here.

Please try booting Beta1 with 'hw-detect/load-ide=true'. Does that help?
Also, please provide the output of 'lspci -nn' and 'lsmod'.
If the above helps, then the last both for a boot with and without that

That's a won't fix. If you choose guided partitioning, you get its defaults,
and those are not tuned for lowmem. You can either change the file system
type before committing the changes, or not use guided partitioning.

That could be ide-generic again. Try booting in rescue mode, mount the
target system, add ide-generic to /etc/initramfs-tools/modules, update the
initramfs and reboot.
