For posterity's sake, there was a slightly smaller workaround here, and
it would be as in the following patch:
--- drivers/net/wireless/rtlwifi/rtl8192se/hw.c 2011-09-29

+ RT_PRINT_DATA(rtlpriv, COMP_INIT, DBG_EMERG, ("MAP\n"),
hwinfo, HWSET_MAX_SIZE_92S);
eeprom_id = *((u16 *)&hwinfo[0]);
It's rather nasty though, as it pretends that dumping the EEPROM data is
happening right before a fatal error has occurred. But there's really no
other way, as using sysfs to set the "global_debuglevel" is not good
enough because the EEPROM data is read right after the module is loaded
(making it hard to set the debuglevel in time).
If this info is useless to you, disregard it!

PS: the EEPROM data I mentioned in my previous message is still the same
though, so I won't bother to repost it.
