A question to all that are running Linux on their TEST, does it recognise 64mb of ram? I have read that the 32mb of ram is a major limitation to the capabilities of Linux on the PS2, so theoretically the 64mb should make it better.
I was going to ask the same thing on that TEST topic, until i saw your post. I already saw a normal PS2 with Linux, and although it works great, it could be better with more ram.
Well no and i'm still searching a way to pass the parameter to the kernel or the option in the config make file. Here's the dmesg output on my DTL-H30102: use boot information at 0x81fff000(old style) boot option string at 0x81fff100: root=/dev/hda1 crtmode=vesa0,60 Loading R5900 MMU routines.

Someone should look at the kernel source code for the PS2 linux kit and see what the memory code looks like (i.e. the code printing the "you have 32mb RAM" message)
