'Sonic Robo Blast 2' is indeed an excellent free game, and - luckily - one which is easy to get running on the Eeepc. I downloaded it this morning onto my Eeepc 701 SD (with standard Xandros OS), and so far it's working fine.
First, follow the instructions (VERY carefully) about pinning your system and adding extra repos available here:

Then download 'Wine' - a program which allows Windows programs to run in a Linux environment (yes, I know that SRB2 is available in a native Linux form, but for various reasons it would probably be easier/safer to just use the Windows version).
Instructions on installing/using Wine can be found here:

I'm running the standard Wine 1.0, and SRB2 works fine under it.
Finally, download the latest .exe file from 'www.srb2.org' (other sites offer the file for download, but they mostly have older and inferior versions).
Right-click on the .exe file and type 'wine' into the 'Open With' field.
Initially, I tried unpacking the file into the standard Linux 'Z: Drive', but experienced some major program issues. However, after removing and reinstalling it in Wine's virtual 'C: Drive' (as recommended in the above Wiki article), it now works fine.
There do seem to be some minor issues:
The music seems distorted, but can be safely turned off without detracting from the game's playability.
Every 30 seconds or so the frame-rate inexplicably drops off for a fraction of a second.
Once or twice their have been peculiar computer freezes while running the game.
However, these are minor issues that have yet to interfere with my enjoyment of Sonic Robo Blast 2.
