Yes there is a way for you to do an update and not lose any homebrew.
Grab WiiMod2.9 < http://gbatemp.net/index.php?showtopic=272321
This is just like using MultiModManager but with slight more options.
Select "System Menu" option
When your done your will have a fresh System Menu installed running off IOS123 version 65535(which is the highest version possible
Now all you need to do is install IOS249 with a version number 65535. You dont have to but if this step is not done IOS249 always gets STUB unless you install it with the max version number. You could always just reinstall it after updating but i'm lazy LoL

Select "System Menu" option
- Choose which System Menu you would like to install; you can choose a System Menu as low as 2.0. (I choose 4.1 cause it the last one to support other region wii games)
- Choose Region U/k/e/j which ever your region is
- Select "Yes" to both Set Revision & Required IOS
- Choose IOS slot the new System Menu will run off (I always choose IOS123 but you can choose any one)
- Set version to 65535 (this will prevent your System Menu from ever updating even from disc or online updates)
