mmmm, not sure which version of Modelsim you are using but my 6.5b version 
complained bitterly and told me to get some more coffee..

After some quick hacking I changed the code into:

type ram_t is protected -- Error in PS
impure function read(a : natural) return std_logic_vector;
procedure write(a : natural; d : std_logic_vector);
end protected ram_t;

type ram_t is protected body
type ram_array_t is array(0 to 127) of std_logic_vector(7 downto 0);
variable ram_array : ram_array_t;

impure function read(a : natural) return std_logic_vector is
begin
return ram_array(a);
end function read;

procedure write(a : natural; d : std_logic_vector) is
begin
ram_array(a) := d;
end procedure write;

end protected body ram_t;

Unfortunately it didn't go through Precision although this might be due to 
me screwing up the code.

[40000]: vhdlorder, Release 2009a.15
[40000]: Syntax error at or near "protected"
[40000]: VHDL file ordering failed.
