Not quite there $1 contains the variable name and is overwritten with "=" newvalue, try:

Code:
awk -F= -v var="$new_value" '/ABCD/ {$2 = var} 1' OFS== file > new_file

MODLOAD(8)						    BSD System Manager's Manual 						MODLOAD(8)

NAME
modload -- load a kernel module SYNOPSIS
modload [-fP] [-b var=boolean] [-i var=integer] [-s var=string] module modload -p [-b var=boolean] [-d var] [-i var=integer] [-m plist] [-s var=string] DESCRIPTION
The modload utility loads a kernel module specified by the module parameter into the running system. Modules are loaded from the default system module areas unless the module parameter contains a path separator character ('/'). The options to modload are as follows: -b var=boolean Pass the module a boolean property with the name var. boolean may be either true or false. -d var When used in conjuction with -m, delete var from the plist specified. -f When a module is loaded, the kernel checks if the module is compatible with the running kernel and will refuse to load mod- ules that are potentially incompatible. This option disables compatibility checks. Note: an incompatible module can cause system instability, including data loss or corruption. This option is also required for re-enabling a builtin module that was disabled using modunload(8). -i var=integer Pass the module an integer property with the name var and integral value integer. -m plist When used in conjuction with -p, merge new options with an existing property list contained in plist. -P This option tells the kernel not to load an associated property list. -p Output a property list suitable for loading along with a module. When using this option, you do not need to specify a mod- ule. Use -m and -d to read and modify an existing property list. -s var=string Pass the module a string property with the name var and string value string. DIAGNOSTICS
The modload utility exits with a status of 0 on success and with a nonzero status if an error occurs. SEE ALSO
module(7), modstat(8), modunload(8) HISTORY
The modload command was designed to be similar in functionality to the corresponding command in SunOS 4.1.3. BSD
