IRIX and Software

Problem with nekoware e-uae

Hi everybody!
Last weekend I tried to install e-uae on my Octane2-R12K/400-V6, IRIX 6.5.29, screen set at 1280x1024, 24 bpp. I used the kickstart and workbench of my old faithful A500, which worked perfectly on WinUAE.
All dependencies are there and the tardist file installed flawlessly. E-uae starts up correctly and allows me to set the ROM path and the virtual disks, then as soon as I depress the "Pause" button it invariably aborts with a useless (at least for me) message about X error messages being asynchronous. No other clues.
Anyone else experienced this problem?
Ah, reducing the screen depth to factory setting (i.e. pseudomap) is even worse - it actually prevents e-uae from running.

Thanks!
