{{{
It's a tricky question . On 4xxx __local mem is really __global mem ( ATI thinks it's too much work to optimize compiler to use 48xx  LDS - although it's possible ). 
On 5xxx __local is LDS - so it's located in simd core.

== Catalyst 10.1 with Ubuntu 9.10 workarounds ==
=== Change the kernel boot option ===
Edit "/etc/default/grub" and execute update-grub. I add "nopat" to GRUB_CMDLINE_LINUX_DEFAULT for Catalyst 10.1.

The configuration file for the grub is at /boot/grub/grub.cfg.
This file is automatically generated by update-grub command.

=== X server setting ===
The default login manager gdm is difficult to properly configure, I install xdm instead of gdm.
The configuration file for xdm is at /etc/X11/xdm directory.

Edit "Xservers" file as
{{{
:0 local /usr/bin/X :0 vt7 -nolisten tcp -ac
}}}
This "-ac" option enable remote applications to access the local X server.
Note this option is generally regarded as "bad" for security. Be careful.
