Was your upgrade a perminant video BIOS upgrade? Sounds like your using a software video BIOS upgrade, I remember I used to use one for my old cl-gd5424. The software BIOS upgrades are basically just DOS device drivers that redirect BIOS functions to the updated routines within its code. If this is your case than it shouldn't work, unless.......
Not sure if this is possible but just brainstorming here: the device driver that redirected the BIOS functions was loaded in high memory which Linux marks as reserved upon bootup thus the device driver code is probably still in memory and the BIOS redirections remain set it might have a chance of working. (Note: that this would probably require that actual memory exist on your system in the high memory area) Another (brainstorming theory) possibility is that the BIOS update overwrites the BIOS shadow of the previous video BIOS if video BIOS shadowing happens to be enabled on your system (I doubt this would work without shadowing as in that case the video BIOS addresses would probably be addresses to ROM). Since you use loadlin, the system is not reset, perhaps your upgrade could actually be made to work. However this is unlikely.
