And the details are in the manpage:

FbTerm supports xterm's 256 color mode extension. The first 16 colors are 
the default terminal colors. Additionally, there's a 6x6x6 color cube, and 
24 grayscale tones.  But xterm's 256 color escape sequences conflict with 
the linux sequences implemented by FbTerm, so private escape sequences 
were introduced to support this feature:

ESC [ 1 ; n }              set foreground color to n (0 - 255)
ESC [ 2 ; n }              set background color to n (0 - 255)
ESC [ 3 ; n ; r ; g ; b }  set color n to (r, g, b) ,  n, r, g, b all in (0 - 
255)

A new terminfo database entry named "fbterm" was added to use these 
private sequences, all program based on terminfo should work with it.  By 
default, FbTerm sets environment variable "TERM" to value "linux", user 
need run "TERM=fbterm /path/to/program" to enable 256 color mode.

Apparently some distros have chosen to enable that 256 color mode by 
default.
