Need to update kernel configs to support DesktopTeam's Hardware Detection spec

[Dan Munckton]

Need to change the values of ...

 * CONFIG_USB_DEVICE_CLASS
 * CONFIG_SYSFS_DEPRECATED
 * CONFIG_SYSFS_DEPRECATED_V2
 * CONFIG_TMPFS_POSIX_ACL

... as specified in the Hardware Detection spec. See section "Kernel configuration" on

https://wiki.ubuntu.com/DesktopTeam/Specs/HardyHardwareDetection

These options are currently set as follows. Note need to check why these options are set slightly differently for ia64.

Raising importance to High apparently the presence of these options can cause race conditions. In particular current udev isn't tested with CONFIG_SYSFS_DEPRECATED=y so there could be loads of problems not yet noticed.

[Dan Munckton (munckfish)]

Nominating linux-ports fix for Intrepid. Note would probably need to rollback or defer the commit for bug #213668 which was pulled in after this one as it's basically an additional feature. Whereas this relates to system stability.

[Dan Munckton (munckfish)]

Relevant changes are present in Jaunty linux-ports 2.6.28-1.6. Closing this.
