The most significant drivers and modules that you should maintain on the x455
are:
Broadcom Gigabit Ethernet
The Broadcom Gigabit Ethernet adapter is supported on Linux with the
"bcm5700" module. This module supports all the 5700 series of Gigabit
adapters from Broadcom. This module comes with SUSE LINUX SLES 8 and
Red Hat EL AS 3.0, and both Broadcom ports are detected during the
installation.
LSI SCSI chipset
The default kernel that comes with SUSE LINUX SLES 8 and Red Hat EL AS
3.0 has the LSI chipset support precompiled. This will automatically support
any SCSI devices connected to your LSI chipset.
ATI Rage XL video controller
The video controller used in the x455 is an ATI Rage XL device. This device is
supported by XFree86, with the "ati" driver. This driver supports almost all the
ATI graphics controllers. ATI controllers are supported on both major versions
of XFree86, the 3.3.6 and the 4.2.1. To follow the status of any supported ATI
graphic device supported by the XFree86 project, see:
http://www.xfree86.org/current/Status6.html#6
For generic information about the status of any driver, see:

ATI also has a support page for Linux, where you may find all the information
you may need for finding any new drivers or simply to know more about ATI's
support of Linux:

XA-64 chipset
At the time of this writing, there was no official kernel update to support the
new 64-bit chipset. The x455 will work in 64-bit native mode without any
kernel patches. If IBM, SUSE LINUX, or Red Hat release any specific patch
for the XA-64 chipset, you will find more information about how to upgrade
your current kernel on the xSeries support page:
