Here was my collected experience on a Centrino machine, before I returned it in favor of an iBook:
The AGP worked in 2.4.21-pre but not in 2.5.68-mm2, regardless of agp_try_unsupported=1. The Radeon 9000 Mobility in the Acer Travelmate is supported in XFree86 4.3.0. Don't know about the IBM.
The IDE DMA seemed to work fine in both 2.4.21 and 2.5.68.
Power management didn't work at all because ACPI is a sick joke. In 2.4 ACPI does nothing, and in 2.5.68 it can put the machine to sleep, but not wake it up. APM could almost wake the system from sleep, but then it crashed immediately. ACPI incorrectly reports the state of the system fans, the battery, the battery charger, and the temperature sensor. In other words, no part of it functions correctly . This is either a problem with Centrino chipset in general or Acer BIOS programming in particular.
CPU frequency scaling didn't work in either kernel but there seem to be rumbles of reverse engineering going on with that.
The wireless doesn't work in any kernel, and Intel have stated specifically on their web site that they have no plans for any future Linux driver for that device.
The Centrino package is altogether hostile to Linux.
