The ioprio_set system call is only available since kernel version 2.6.13. The 
toolchains from Dan Kegel's tool use older kernel headers (2.6.12). So, your 
options are:

1. Disable the ionice Busybox applet.

2. Use a newer toolcahin (from CodeSourcery, for example)

3. Copy a newer kernel header file into your current toolchain

The same here. EV_SW first appeared in kernel version 2.6.13, and SW_LID in 
version 2.6.17.
