It'd be rather useful for debian-installer if we could get hold of accurate firmware information on whether only 32-bit kernels are supported, only 64-bit kernels, or both; this would allow us to present an accurate menu of kernel packages if more than one is available, rather than the user having to guess. This patch attempts to expose it in cpuinfo. I adjusted pdc_model_capabilities to cope with a potential PDC_INVALID_ARG return as the firmware manual instructs, by assuming 32-bit only. This may be the wrong place for it. I made up user-visible capability names by total fiat and for the moment ignored the other bits that may appear in the capabilities word. I have no PA-RISC machine myself to test on, and no PA experience either, so I rather hope that somebody will kind-heartedly take this and fix it up if needed. I ran it past Dann Frazier on IRC and he said "looks good to me", but I think without testing. Also, this is against the Ubuntu 2.6.28 kernel tree since that's what I had handy and I was a bit tight on disk space to slurp down another tree. Sorry if it's skewed in any relevant way; I'll be happy to adjust if necessary. Thanks in advance!
