We need to detect if we're running on an affected system somehow. Does the SmartFirmware version number (1.3 here) completely reflect wether the problem is present, or do we need to check /openprom/model too? > 17:19 the problem is that the graphic memory is mapped at the start, and the firmware is located from 16MB to 24MB or so, maybe a bit more with stack. > 17:20 normally; the area between 0 and 16MB, except for the interrupt vectors, should be available. I'm not sure how big is the interrupt vector, but since we succesfuly loaded GRUB at 0x10000, I think it's safe to assume that as the lower bound. As for the higher bound, is 0x1000000 exactly it, or was that a rough estimate? -- Robert Millan My spam trap is honeypot@aybabtu.com. Note: this address is only intended for spam harvesters.
