By default, the X100e ships with bluetooth disabled. There is no option for it in the BIOS; currently the only way to enable it is to install Hotkey Features Integration  in Windows, and then press Fn-F5 to bring up the wireless control panel.
By default the audio jack doesn't disable the internal speakers in Linux, in fact it doesn't seem to work at all (at least in Ubuntu 10.04 -- apparently in Mint it works for some people). A workaround for this is to edit /etc/modprobe.d/alsa-base.conf and add the following line:
options snd-hda-intel model=olpc-xo-1_5 and then restart alsa (or reboot).
As of the 2.6.34 kernel  the above workaround should no longer be needed.
In many distros, Ubuntu included, the r8192se module that ships with the kernel will load and successfully connect to an AP and even succeed with DHCP, but still pass no network traffic. A workaround is to get the latest driver code from realtek , unpack it and do a 'make' (assuming you have the equivalent of build-essentials installed) and then from the build directory, copy ./HAL/rtl8192/r8192se_pci.ko over top of e.g. /lib/modules/$(uname -r)/kernel/ubuntu/rtl8192se/r8192se_pci.ko (will vary depending on distro) and then reload the module/your wireless manager/etc.
Note: as of kernel 2.6.32-22.33 wireless should work out of the box (the latest kernel on Ubuntu Lynx has these updates)
The Intel Wifi Link 5100 (AGN) half height card from the T400/T400s works without a BIOS error on the X100e.
Hangs on changing brightness and switching power modes
Some x100e's will hang when you unplug the power, or change the brightness in X. To solve this, upgrade to the latest BIOS and optionally install the proprietary FGLRX drivers. I updated the bios like this: BIOS_Upgrade/X_Series#Approach_10:_Booting_the_Lenovo_ISO_image_using_Grub_and_SysLinux
Under kernel 2.6.35-rc4 (and possibly 2.6.34), the open source Radeon drivers work properly with brightness controls, and don't have the same negative effects with compiz that the FGLRX drivers do.
