Well...I learnt something from a Kanotix live cd, with a 2.6.24 kernel, like Chris Snook suggested. I can boot "nosmp noapic", instead of "acpi=off noapic", and if I do that acpi works and the wireless appears. So that is something. Unfortunately the process switches of half the CPU, so it doesn't seem like a good idea. And half the usb sockets are still dead. And the wireless card looks like an ndiswrapper case... Also, "lsusb" or "cat /proc/bus/usb/devices" have an interesting behaviour, with either boot options: normally they look OK, e.g.: Bus 003 Device 001: ID 0000:0000 Bus 002 Device 002: ID 05e3:1205 Genesys Logic, Inc. Afilias Optical Mouse H3003 Bus 002 Device 001: ID 0000:0000 Bus 001 Device 003: ID 0bda:0158 Realtek Semiconductor Corp. Bus 001 Device 001: ID 0000:0000 but if I plug something into one of the unresponsive sockets then they freeze and never work again. There is nothing in the log file. So presumably the usb system is trying to work and dying?
